> The UI is not a *lot* worse than windows 7 because the UI is nearly the same as 7. You are not forced to use metro. You can consider it just one more of many features of windows you never need to use.
My first thought was that this statement was profoundly disingenuous, but then I realized that you may have used Win8 for awhile, put in a start menu replacement, disabled the hot corners and all the Metro stuff, went through file associations and changed every one from a Metro app to something that isn't Metro, and if on a laptop made the required registry changes to make the screen resolution and things like ACPI work correctly. You may not even remember having to do all of that. Or you may have been profoundly lucky and not had to do some of it. (The screen res and acpi issues seem to affect only laptops from certain vendors.) You may even not have a use for the control panel items that are in tablet-friendly-but-KVM-unfriendly places now. Or maybe you just put the effort in to learn all the foibles of using a touch based UI on a non-touch machine. I am not looking over your shoulder, so I don't know.
The thing about Win8 is that the "extra UI choice" is not really a choice, it's something I had to dink with every time I touched the computer. It was a Bad User Experience, and frankly, it was easier to go back to Win7 than it was to twist Win8 into something I could work with comfortably.
As to considering leaving Windows carefully, I use the Adobe creative suite extensively in my work. If it's ever ported to Linux (and runs well) I'm outta here. (I've supported Linux both server and (a few) desktops, and I'm comfortable with it.) It *is* ported to Macintosh. I'm not a big fan of Apple (their products are boutique priced and the cult-like fanbase is irritating) but they *do* run the software I need. Just sayin'.
