Acer's Windows-powered Iconia W500 up for pre-order for $549, ships April 15th

Acer already announced UK pricing for the Windows 7 and Android Honeycomb versions of its Iconia Tab, and now it's ready to take both stateside. Days after Best Buy started taking pre-orders for the Android 3.0-powered Iconia Tab A500, the Windows-based W500 has shown up on B&H's site for $549. Like its cousin, the W500 has a 10.1-inch (1280 x 800) display, HDMI-out and dual cameras, though it steps up to 2GB of RAM, 32GB of storage, AMD Radeon HD 6250 graphics, and a 1GHz Ontario (C-50) AMD Fusion APU. It also comes with a keyboard dock, putting it in the same price range as ASUS's Android-based Eee Transformer, which costs less but doesn't include its similar-looking keyboard. Acer rates the W500's three-cell battery at up to six hours -- a far cry from the iPad's promised 10-hours and, perhaps, a good reason to wait for slates featuring that lower-power Fusion APU AMD's been shopping around to tablet makers. B&H says it'll ship starting April 15th, but head on over to its website if you're psyched enough to place an order now. Or you can keep saving your pennies for Acer's other Iconia.
