A fair comparison of the iPad and its primary competition.
As you can see, the iPad fails at beating the competition.
But seriously, HP did this years ago and nobody paid attention because it was HP (I'm not talking about the HP Slate they're coming out with, though it was very similar to that). Apple just steals other peoples' ideas and claims to "innovate." Better marketing isn't really innovation.
Not that this is even that great of an idea in the first place. If I want a tablet PC, I'll get a tablet PC; if I want a netbook, I'll get a netbook; if I want an iPhone, I'll get a Nexus One.
