Win8 doesn't bother me [doesn't excite me either] because I'm used to trying to make software do what I want -- I guess that comes partly from the old days when software did much less & was anything but user friendly -- partly from a lifelong habit of using whatever was lying around, fixing &/or making things from odds & ends rather than expecting to find the perfect solution on a store shelf. When the 1st win8 preview came out I promptly turned off Metro, & when MS fixed it so that you couldn't, ignored the touchscreen interface as best I could. It was a Huge reality check [and I'm ashamed to say a Huge source of entertainment] when my son 1st laid his hands on win8 over the weekend, installing the win8 Enterprise trial.
I hadn't paid a lot of attention to how often win8 works illogically -- I just accept such stuff as stupid design & get on with it -- but it really & truly drove my son nuts. And he wasn't trying to use the touchscreen interface, nor had he gotten around to missing the Start Menu yet. It's making me reconsider much of everything I thought about the new OS.
Now my son may get used to it, may even turn out to be a very big fan of win8 once he puts his initial shocks [& there were Many] behind him -- or I may find he did a quick format last night, getting rid of every trace. I have no idea how many people there are out there that will have an identical reaction [or worse] the 1st time they introduce themselves to win8. I've no idea how many of those people will be able to leave their 1st impressions behind, figuring out how to live with win8 on their own terms. But I can say now that I better appreciate how some people can truly loath this latest version from Microsoft. In my son's case it wasn't lack of knowledge, nor fear of something new &/or the unknown, but more his reaction to a cascade of bad [perhaps even stupid] decisions that were made designing win8. From now on when someone says they hate Microsoft's newest, I'll take them at their word.
So if you're thinking about running win8, IMHO leave youself a way out, making sure you can go back to your old Windows version as easily & quickly as possible. You can try it in a VM or try it alongside the Windows you use now without compromising what you already have. If you decide to upgrade the Windows you have now without trying win8 1st, at least create a full disk image backup, making sure you know how to restore it. I realize not everyone will react to win8 the same way as my son did -- I didn't -- but I can't imagine what it would be like to go through that & not have an easy way out.
