It's not really hate. But it is a decision to avoid hassles a year or three or ten down the road, I've had to deal with plenty of other people's broken ME/Vista problems, more than enough to make me incredibly happy my deliberately "obsolete" Windows machinery always worked perfectly. I'm sure Win8 is good, based largely on Win7 and all, but it just demonstrates that Microsoft's focus has been on optimizing elements and directions which have nothing to do with the way I actually use a computer. If I want a mobile touchscreen OS, I'll buy a toy with Android or iOS.
Maybe my "hate" is just angst at the utterly ripoff prices I paid for a couple of Win7 Ultimate editions, the same day I downloaded half a dozen free opensource linux distros. Won't fall into that trap again.
