Agreed
I have an iPad.... and I'd MUCH rather have one of these sexy new gadgets that I can use in every scenario. The only trouble for me is figuring out which one I will settle on. HP's Envy x2 would be perfect if it came with a wacom style pen for taking notes.
As I want to hold out for reviews anyway, I may just end up waiting for the Surface Pro since it really is the best to cover all angles imo... lightweight, premium performance specs, easy k/b solution, and a pen. I love Toshiba's slider as well though and will probably get it... though not so much as a tablet replacement, that will be my ultrabook purchase for the year.
