It's sort of hard to believe, but the first sub-10-inch Windows 8 tablet only just went on sale two weeks ago. For now, at least, the Acer Iconia W3 is the only 8-inch option available, though it surely won't be the last. What's more, it arrives in lockstep with Windows 8.1, which brings a few improvements that might make an e-reader-sized tablet like this especially easy to use (think: the ability to snap photos from the lock screen). And with a starting price of $380 (Microsoft Office included!) it could be a great buy among Windows tablets, period, regardless of screen size. Let's see if it really is.
