And then there were two: if we're counting correctly, Acer's Iconia Tab A510 just became the second quad-core Tegra 3 tablet to go on sale in the United States. While it doesn't have an optional keyboard dock like the Asus Transformer Prime, the 10.1-inch Android 4.0 slate does have a fairly sleek design, 32GB of storage and a sizable 9800mAh battery pack to its name, and — assuming you're not holding out for a $199 Tegra 3 — you can pick it up for $449.99 at Acer's website today.

If you're not ready for the latest and greatest, though, you'd probably be happy to hear that Acer's existing dual-core Iconia Tab A500 and A100 tablets will be getting an update to Android 4.0 quite soon. Assuming you aren't already running a leaked version of the Ice Cream Sandwich update, a support page at Acer says that the legitimate builds of the software will be rolling out to both tablets starting on April 27th in the US, and for the A100 on April 25th in Latin American and May 3rd in Canada.
