All you need to do is to update to new Ice Cream Sandwich 4.03 version 9.4.2.28 and the update will finally get you the precious face unlock feature. Apart from that you can expect to see:
• GPS dongle fix and local notification
• Ethernet UI support to set Ethernet connect policy when screen off
• Add system bar lock settings for showing/hiding system info
• Enable face unlock feature
• Support Bluetooth HDP
• Third party app upgrades
• Other bug fixes
The model we tested never actually suffered from the Wifi bug and Wifi was always working at really high speeds. The only issue that we hope to see gone is the random reboots with Chrome beta browser, but this can probably also be blamed on Google and the Chrome team, not just Asus.
We have to add that Transformer Prime is a tablet that gives you 15+ hours of battery life when connected to the keyboard dock, which definitely beats any Ultrabook. To be fair, Core i5 and Core i7 ultrabooks do work faster and they can cope with a lot more serious applications, but they can’t match the Transformer in battery life
