I don't think I'd ever want one. The screen is just way too small for me. I can see the appeal of a machine such as this though. A relative has one of the Toshiba ultra slim laptops (10" I think, not sure which model etc) and it always amazes me when she pulls it out of her handbag. It is also REALLY REALLY light, which I think is important...cmon apple, i wanna see the 15" MBP go on a diet - max 500g.
