What's left to say? The iPad defines the tablet market and its second generation sets the competitive standards, from the screen size and memory to software features and user interface. No, it still doesn't do Flash and doesn't have a USB port, but buyers don't seem to care since no one can match its fluid, responsive touch interface or its rich App Store selection.
Biggest pro for enterprises: Your employees want it, or already have it.
Biggest con for enterprises: Limited external connectivity. No Flash apps. New model due shortly.
Notable differences from rivals: Largest application selection, by far. Most mature, polished OS.
Pricing: Wi-Fi, 16/32/64 GB -- $499/$599/$699. Wi-Fi + cellular, 16/32/64 GB -- $629/$729/$829.
