I'd enjoy an "instant-on" version of Windows if they focused it on productivity software and casual access to the internet. I'd also need to see it improve laptop battery life by a fair amount. Let's speculate: if this version of Windows allowed you to run Microsoft Office, Internet Explorer (with overhead plugins turned off, such as FlashPlayer) and gave you access to file servers (FTP, SSH, etc.) and sported a 50% battery life improvement, I'd use it! This is a perfect setup for what I need from my laptop when I'm going about my day from classes and meetings.
