For the past few months most of the tablets we've seen have been running Windows 8, but at CES this week Android tablets have seen a resurgence of sorts, starting with two from Vizio and now the Iconia B1-A71 from Acer. It's hardly a flagship tablet. Quite the opposite actually: it has a dual-core Mediatek processor, 512MB of RAM, 8GB of built-in storage, a 7-inch 1,024 x 600 display and a single 0.3-megapixel camera. Overall, the build quality and screen aren't nearly as nice as what you'll get on the Nexus 7. Still, for $150
