We might as well start off with the iPad since it's the most popular tablet and it's the standard to which other tablets will be held. The iPad's specs are indeed impressive, as it includes a 1GHz Apple A4 processor, a 9.7-inch screen with a resolution of 1024 x 768 pixels and connectivity with both Wi-Fi and GSM-based 3G networks. Combine this with the wide variety of applications available in the iTunes App Store, and you've got a tablet that presents a strong standard for the competition.
