I'm thinking of buying a MacBook but I have one reservation. I'm moving from a Powerbook 12"... What's the consensus on the MacBook keyboard in terms of ease & comfort of use? I write for a living so a good keyboard is pretty essential. I've always been mostly satisfied with my powerbook keyboard, it's pretty comfortable although I occasionally mash a neighbouring button with my big clumsy fingers. The MacBook keyboard looks a little... weird. How is it?
