Sure, 5,000-plus attendees received limited edition Android 3.0 "Honeycomb"-based Samsung Galaxy Tab 10.1 tablets like this one at Google I/O May 10.
But it looks like those who purchase or otherwise procure the commercial version will get the 10.1 with Android 3.1, the freshest version of Honeycomb currently only available on the Motorola Xoom.
Honeycomb 3.1 essentially is an incremental upgrade, boasting expandable widgets and access to the Android Movies service, and Adobe Flash Player 10.2 support (though I was able to upgrade to Flash 10.3 to watch Amazon Instant Video on my I/O tab last week).
Honeycomb 3.1 also supports two new APIs, the USB host API and Open Accessory API.
For Honeycomb devices that support USB host mode, applications can now manage USB peripherals such as voice over IP headsets, mice, trackballs, joysticks, gamepads and others.
The Open Accessory API allows Android applications to integrate and work with musical equipment, exercise equipment and robotics systems. Honeycomb 3.1 will also be ported to Google TV later this summer.
This will be a nice incentive for Honeycomb fans expecting a little more bang for their buck. By the way, the Tab 10.1 is expected to run $499 for 16GB, $599 for 32GB.
