Portability is all about surface area, and weight (and to a certain extent battery life & connectivity). They seem to have completely missed the point(s), by not improving any of them.
I agree Bartmanekul, you will still put it in the same bag as your old 15.4" or whatever laptop, and it still weighs the same, so what's changed? Oh hang on, I forgot, you can put it in the mail and post it to someone easier..... how many times do you post your




laptop?
