ASUS's $499 Eee Pad Transformer Prime was not only the first tablet to rock Nvidia's super-powered quad-core Tegra 3 CPU, it was also one of the first tablets to throw off the shackles of Android Honeycomb and get an upgrade to Ice Cream Sandwich. Unfortunately, the upgrade wasn't exactly a step forward in all respects.
The over-the-air update may have given users access to the operating system, just not all of its coolest features. Notable features left out of the update included Face Unlock, the favorites tray, and the ability to close browser tabs by swiping them away. Still, if you're looking for the most powerful tablet on the market with access to Ice Cream Sandwich, the Transformer Prime is it.
