PC World – The first major update to Google’s Honeycomb platform, Android 3.1, was announced last week at the Google I/O developer event, and it’s slowly rolling out as an over-the-air update to mobile broadband-connected Motorola Xoom tablets. When announced, Google was vague about when we could expect Android 3.1 on other Honeycomb tablets, but today saw update details flying across the Web for both the Acer Iconia A500 and the Asus EeePad Transformer.
