With just its name alone, the ASUS Eee Pad Transformer Prime ($500) could possible be the coolest tablet in the market. It may not come with the Spark, but the Transformer Prime features a Nvidia quad-core Tegra 3 processor, 10.1-inch 1280 x 800 resolution Super IPS+ display, an 8.0-megapixel camera with a flash and a back-illuminated CMOS sensor, a battery that last up to 12 hours on a single charge, and an optional keyboard dock .
