You just don't get it, do you. This is a kindle that browses the web in full colour, plays video and lets you check your email. Apple already make the best desktops and notebooks in the world, this is a NEW device. Open your mind. A pro work tool would not retail at $499. This is a simple device designed to fulfil the basic needs of normal home computer users, not IT professionals. Check your email, browse the web, play music, play the occasional game, read a book/magazine. That's all it does, that's all it's designed to do. That's the point. If you're comparing it to a notebook, desktop or fully functional OS tablet device, you've missed the point.
I wanna sit on the sofa with a glass of wine in one hand, this on my lap while i read, or watch a movie, or browse the net, or catch up on my email. That is all. It will do it well.
