I don't really feel any need to jump on the tablet bandwagon, thanks. I still fail to see any concrete advantage to something that's either an oversized iPhone minus the phone, or an underpowered laptop minus the keyboard.
Bandwagon? It's actually just a logical step for computers to take. I'm sure there were people ranting and raving that they weren't going to jump onto the "Mouse controlled graphical user interface" bandwagon in the mid 80's

I don't need a tablet computer, but I have friends with iPads and I have little doubt that I'll get an iPad within the next year or so. They are remarkably natural devices to use, and would replace my laptop for 100% of casual use.
