It may have taken a little longer than the Kindle Fire, but Barnes & Noble's Nook Tablet has finally gotten the latest version of Android thanks to Cyanogenmod developers. As usual, this release is in no way official and is only a work of the development community, but even so the alpha build appears to run fairly well on the Tablet.
Of course, there are still quite a few things that don't work exactly right, like hardware accelerated graphics, the microphone, Bluetooth, and hardware composition. There are also sure to be many other small bugs and quirks that make daily use less than satisfying. However, in the video above Ice Cream Sandwich seems to run very smoothly, and all the basic functions like WiFi, the accelerometer, the Android Market, the display, and sound do work fine, so you could run the alpha 0 as your main software if you wanted to.
It might not be ready for the average user yet, but Ice Cream Sandwich on the Nook Tablet is a testament to how far the development has come. Between this and the release of a cheaper Nook Tablet, it looks like Barnes & Noble could give Amazon a run for their money, thanks in large part to the dedicated developers behind their hardware.[Nothing But Tablets]
