It cannot replace your netbook and laptop, since, as robot said, Android is mobile operating system. I'm quite satisfied with my Edge and my 10'' netbook, so I'm thinking of selling my desktop computer. You can sure use the Edge for browsing online and for some simple document editing, but you need at least one laptop/netbook. I also get backache from my desktop PC, but not when I'm using my netbook or my Edge. I can't wait to buy a netbook with a Pixel Qi screen, it would make a great pair with the EE.
