Methinks Win 8 will quickly go the way of Vista. It is widely and deservedly hated. It's an operating system designed for those with no interest in operating a system. It's the software version of Big Brother.
I actually like 7. And of course, YES, 98 was the best, but that's so many generations ago, it'll never come back. (Actually, I ran WinMe for years and LOVED it, but I appreciated, unlike its detractors did, that is was just 98 with some very cute lipstick and earrings.)
Taxed has tried repeatedly to turn me on to Linus' thing, and I've tried. But DAMN! It's a lot prettier and smarter than it used to be, but I don't want to have to learn Commodore Basic all over again just to install a driver. I don't care for a developer community with the mentality that you SHOULD HAVE ALREADY LEARNED their non-English argot just to get your printer going. (Anyone who complains about poor hardware support from Microsoft should try any version of Linux -- you will come running back.) Also, I've learned the hard way that trying Linux -- at least Ubuntu 10 and 12.04 -- as a dual-boot OS on a Win XP system is a VERY bad idea. Linux makes unauthorized changes to Windows files, rendering them useless.
Linux may be a great thing as a sole OS, but I don't recommend it as part of a dual-boot system.
