Great article. I'm really looking forward to the simplification of our display stack, and the improvements and innovations that surely will stem from it.
Also, I'm really looking forward to some performance improvements and a nice multitouch future.
Working on a computer all day long, I've become increasingly frustrated with its bad input system. Keyboard is very nice for writing code, but when working with big drawings/design/CSS and HTML (etc), it just doesn't cut it. I'd like to have a big screen and use my hands however I want. Do things quicker and not feel limited by the computer.
