The iPad is great on many levels. It's good for reading books, playing games, productivity, etc. It's also great for keeping parents sane, which is a whole other post for another day. In fact, I already wrote that post for CNN and it got a ton of attention.
But, for me, the iPad is mostly about business productivity. That's been the beef with the tablet since day one -- that it was an overblown couch jockeying laptop wannabe. Guess that's why Apple took the effort to explain to you why the device is made for business.
