It is more than a gadget--it is my entertainment computer. I love being able to consume movies, books, You Tube, personal email, music, and news whereever I want at home. And no maintenance hassles! The battery life is a big deal, if you have little kids and travel. Flying over the holidays, it seemed like all the parents had one. I was so happy not to lug my laptop along with the car seats!
I don't mind typing on the screen, but I hope they fix some awkward things like no backspace and auto-capitalization.
For work I'd rather have my laptop for rapid typing, bigger screen, etc.
