How about really rethinking the default UI. I currently have my start menu on the right, and the tabs of my browser on the left, because that is where I have more space thanks to the new 16:9 screen ratios that the industry has standardized on. Why not have the Title bar on the left or right, or at least customizable to be.
They finally have Windows Update usable, after 15years of working with it, so why not let other companies, such as Adobe, use that technology for their updates, for a price, of course.
Why not have a screen when you first start the computer that will walk you through choices of antivirus, and anti-malware.
Oh yeah, when are we going to get a Mac OS like, as in the functionality, quick bar, with out having to rely on these things that can't work with windows explorer.
