At 9:29, the line to get into the #io12 keynote hasn't even advanced to the door of the hall. So much for the 9:30 start.

— Rob Pegoraro (@robpegoraro) June 27, 2012

And we're rolling, even as attendees still stream into the hall. Keynote starts with a look at Android 4.1, Jelly Bean. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

A major part of 4.1 is "Project Butter"–performance tuning to eliminate laggy screen refresh and touchscreen responsiveness. #io12

The idea is to push delays below 16 ms, which they say is the limit of the nervous system's ability to perceive something. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Demoing how existing onscreen icons rearrange themselves automatically when you add a widget in JB. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Google voice typing now built-in to Android to work offline. Unsaid: unlike a certain other smartphone OS's speech input. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Accessibility upgraded in JB with support for Bluetooth Braille hardware. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

JB's camera app speeds up reviewing photos you've already taken with a scrolling filmstrip view. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Haha: Now talking up Android Beam, which I couldn't get to work earlier this morning. In JB, you can share more types of content. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

@robpegoraro I hope they announce that the longer it takes a company to update their phones, the lower their search results will appear.

— Adam R (@inmostlight) June 27, 2012

JB's search has a new UI that directly presents relevant results, like how desktop search now works. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

And voice input in JB's search can yield those results–ask "what is the definition of a robot" and it speaks it back. Very Siri-ous. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Google Now data-mines your life and location to provide personalized navigation and location search results. THIS IS MINORITY REPORT.

— saschasegan (@saschasegan) June 27, 2012

Google Now: JB search feature provides customized results based on your calendar, contacts, location, etc. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Demo: invoke Google Now by swiping up from bottom of the screen, and it provides your agenda. Seems like a personal assistant app. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

If I compare Google Now's agent-type "help you run your life" behavior to Magic Cap's ambitions, will anybody pick up that reference? #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

— Rob Pegoraro (@robpegoraro) June 27, 2012

JB ships as an over-the-air update to… well, probably not your Android device in July, released as open-source then too. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Google's PDK–Platform Developer Kit–gives earlier access to new versions and will supposedly yield faster updates. We. Shall. See. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Google Play Store updates: 600,000 apps and games, 20 billion app installs, added carrier billing support (including Sprint). #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Paid apps will be encrypted to the device to thwart software fraud. "Smart" updates will only download new code, not the entire app. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Reminder: "JB" is short for the Jelly Bean 4.1 edition of Android, not the Jim Beam edition. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Play Store adding purchases of TV shows and episodes from Disney, ABC, NBC, Sony, Paramount, plus magazines. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

"And, uh, speaking of tablets…" Now talking about the Nexus tablet. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Nexus 7, built by Asus, has 7-in. screen, runs JB. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Nexus 7 spec-fest: 1280 x 800 LCD, Tegra 3 chipset w/ quad-core CPU, 12-core GPU, front camera, 9 hours HD video on battery, 12 ozs. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Nexus 7's home screen has Google Play front-and-center. Somewhat like Amazon content on the Kindle Fire. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Magazine-reading demo on the Nexus 7 features some tasteful female photos from Shape magazine. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

"What's this song?" widget IDs songs, links you to the Play Store to buy them. Buh-bye, Shazam. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Chrome is the standard browser on the Nexus 7. Does this mean text editing in that app is no longer unlike in other Android apps? #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Maps in the Nexus 7 include photos of the inside of some establishments that you can pan around. Also: offline mode included. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Now demoing games performance on the Nexus 7 with its graphics processing unit, gyroscope and accelerometer. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Nexus 7 pre-order today for $199, with $25 Play Store credit and free Transformers: Dark of the Moon flick. Ships mid-July. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

And now introducing the Nexus Q, a tiny spherical media streamer that is Google's first venture into consumer electronics. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

.@JohnPaczkowski "missed opportunity to arrange ports in bowling ball format"; @Ihnatko: "looks like the training droid from "Star Wars."

— Rob Pegoraro (@robpegoraro) June 27, 2012

Nexus Q includes same chipset as the Galaxy Nexus and can talk to Android phones via NFC. Micro-USB port allows "general hackability." #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Nexus Q allows multi-zone playback (hi, Sonos!) and lets people guest-DJ from their own Android devices. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

And Nexus Q includes its own speaker. Sort of like an iPhone dock without a dock, or iPhone support. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Nexus Q available for pre-order today for $299, ships mid-July. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Roku and Apple TV have yet to break into the mainstream at $50 and $100, so Google is trying it at $300. Sure, that'll work.

— Jamie Lendino (@jlendino) June 27, 2012

Google's Vic Gundotra back onstage, noting that tomorrow morning will be Google+'s one-year anniversary. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Yes, that's welcome news. cc @mdaisey RT @cjoh So the Nexus Q is manufactured in the United States. That's pretty awesome.

— Rob Pegoraro (@robpegoraro) June 27, 2012

Gundotra: 250 million+ G+ users, 150 million+ monthly active users, 50% sign on every day. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

More G+ users from mobile than from desktop. And now: Android tablet app for G+. (reaction outside this building: #crickets)

— Rob Pegoraro (@robpegoraro) June 27, 2012

Good feature in this new tablet app: Google+ hangouts now switch video based on who's talking. Oh, and there's an iPad version too. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Last sentence really deserved a #buryingthelede hashtag.

— Rob Pegoraro (@robpegoraro) June 27, 2012

One more G+ announcement: event planning that extends to the pre- and post-even phases. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Since nobody has gotten this category right in a couple of decades, I'm happy to see Google take a crack at it. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

G+ invites feature high-res photos (sort of like @pingg) and silly unfolding-envelope animations like @paperlesspost. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Look, here I am in 2007 wondering why Google had no event-invitation service: http://t.co/uMkLfMrt #io12 #humblebrag

— Rob Pegoraro (@robpegoraro) June 27, 2012

"Party mode" allows for real-time photo sharing through G+ event pages. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

After the event, G+ invites feature all shared photos in chronological order, with pics that got the most engagement at the top. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Sergei Brin just walked on stage, wearing those goofy Google glasses to demo them. "This could go wrong in about 500 different ways." #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

A friend of Brin's is wearing those glasses. In a blimp overhead. Which he's about to parachute out of. Whoah. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Live hangout from the glasses. #blimpcam #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Now THAT's how you do a keynote: a guy is about to jump out of an airplane over San Francisco, live, wearing Google Glass.

— Andy Ihnatko (@Ihnatko) June 27, 2012

This is pretty insane. Approaching Tony Stark territory.

— Rob Pegoraro (@robpegoraro) June 27, 2012

Yes, a man wearing a wingsuit is about to jump out over S.F. while streaming his perspective from a computerized visor. Holy shit. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

And we're in the air. Four skydivers livestreaming over S.F. Chutes open–landed on Moscone West's roof. Craziest keynote stunt ever. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

The skydivers delivered a package, which is now being delivered by a guy rappelling down the side of the building. (What, no jetpack?)

— Rob Pegoraro (@robpegoraro) June 27, 2012

And finally, bike messengers raced through the hall and onto the stage. Place pretty much went nuts. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

As we catch our breath, we're getting a close-up look at how the Glass visor works and was developed. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Glass looks somewhat unobtrusive, "weighs less on your nose than many sunglasses." (What about chunky hipster glasses?) #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Demoing how you can use these things to take photos, video anywhere–running, playing tennis, jumping into a ball pit. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Next week, Steve Ballmer will demonstrate the Microsoft Surface by using it from the inside of an under water volcano. On a snowboard.

— Clay Johnson (@cjoh) June 27, 2012

@robpegoraro Rob, this Glass thing might have helped with the Endeavour liftoff. Not having to choose to watch with eyes or camera.

— Chris Smith (@cswriter) June 27, 2012

Discussion of how you can use Glasses to record your life is leaving out the homemade-porn angle. Oh, like you weren't thinking of that too.

— Rob Pegoraro (@robpegoraro) June 27, 2012

They're emphasizing how Glasses let you take photos of babies without distracting them. But babies *love* pulling glasses off faces. #io12

— Rob Pegoraro (@robpegoraro) June 27, 2012

Google is serious about #projectglass. I've learned they've hired hardware engineers away from $AAPL to work on it @CNBC

— Jon Fortt (@jonfortt) June 27, 2012

Google Glass Explorer Edition available for pre-order to U.S.-based #io12 attendees. Ships "early next year," $1500.

— Rob Pegoraro (@robpegoraro) June 27, 2012

And now poor Vic Gundotra has to finish his Events demo and wrap up the conference after all that. Kind of a timeslot fail.

— Rob Pegoraro (@robpegoraro) June 27, 2012

First official G+ Events event will be tonight's #io12 party, featuring @train and @pauloakenfold

— Rob Pegoraro (@robpegoraro) June 27, 2012

Very loud applause at reveal that all #io12 attendees get the new Galaxy Nexus phone, Nexus 7 tablet, Nexus Q.

— Rob Pegoraro (@robpegoraro) June 27, 2012

BTW, major thanks to Google PR for providing–get this–Ethernet connections in the press seats.

— Rob Pegoraro (@robpegoraro) June 27, 2012
