I have not found a way to instruct it (native browser) to use the desktop agent. It really makes me mad, especially with Gmail. I'm basically using Dolphin but it crashes unexpectedly every now and then. I hope developers come up with an upgrade soon to address these shortcomings.
The Iconia is a decent tablet for the money.
Oh, Gtalk shows some weird behavior as far as the front facing camera. It just shifts positions and sometimes it turns totally black. Google or Acer should fix that asap.
