The Acer Iconia A100 has just received wide spread release of Google Android 4.0! This brings added responsiveness to the tablet and greater functionality! The app menu interface has undergone a revision and seems more fluid in the way different menus are displayed. Many apps such as Adobe Flash and Google + have also been optimized for ICS and they join a growing list of programs that are geared towards this new OS.
Personally I liked the new way the gallery was setup, it seems more intuitive to browse for pictures. The keyboard is also a little bit more responsive and maintains a distinctive ICS flavor.
