^^ Buy linux? Why on earth would anyone need to do that? I haven't spent a dime on anything I'm running. Most linux programs are open source. I'm sure there's some commercial software available, but I have yet to run into any, personally. I remember it being hard as hell to find free software on windows, as it usually turned out to be trial software or pseudo-shareware. As far as I know, even if you need some sort of professional software for linux, you can often find it for free. Perhaps you have a much greater need for very specific professional software than myself or most people I know.
Also, I haven't noticed a whole lot of change in Ubuntu for the last few releases, other than running smoother and improved compatibility. If I'm understanding what you're saying about optimization, I would say that most linux platforms seem specifically designed for that (Xubuntu, for instance). Not to mention that there's generally a linux platform designed to run on practically anything with a hard drive.
Honestly, I know very little about computers, but the little bit I do know, I've learned from the time I've spent with Ubuntu.
