When our Matt got hands-on with the S1 and S2, they were only running Honeycomb 3.0, but judging by some leaked—and then pulled—screenshots on Sony's site, 3.2 might make an appearance.
Remember the Eee Pad Slider from way way back? We certainly do. Which is why it's excellent to see it finally come out, in all its full QWERTY keyboard, Android 3.1-having glory.
Android 3.2 is an unexpected little update, especially with Ice Cream Sandwich coming later this year. But good on Google for making its less-than-amazing Android tablets a little bit better all the time until that major new hotness happens.
