Want an early glimpse of the VivoTab RT without having to attend ASUS' special event? Thanks to our tipster, you've got it. An Office Depot has received at least one example of the Windows RT slate a full three days in advance. The short impressions: it's an "awesome" Tegra 3-packing tablet, although the OS reportedly chews up more than half of the 32GB of storage, and USB depends on an adapter if you're not relying on the keyboard. While price wasn't immediately available, we're not expecting retail to deviate greatly from the $599 pre-order formula.
