A few years ago, I would have leapt on the change. I was using Linux as my primary desktop and dual-booting into Windows for any game that didn't work well enough under Wine or Crossover Games (since I was in the middle of my Guild Wars craze at the time, that wasn't a huge problem).
For the past few years, though, the Linux software community has been in the process of willfully self-destructing, mostly thanks to Canonical, who makes the biggest "Desktop" Linux distribution called "Ubuntu" (though many of the other big projects have their own, unrelated problems. More on that below) and their apparent obsession with copying anything Apple does, and doing so badly.
Windows 8 isn't the first OS to make the stupid decision to make the user pretend that their PC is a tablet, completely disregarding the entirely different use cases for the two classes of device. Ubuntu and its horrible "Unity" interface did that Oct, 2010, and it was a horrible idea then, too. Of course, Ubuntu had been messing around with de facto standard UI conventions before that, too (moving window control buttons around for no good reason, e.g.).
The GNOME desktop project followed not far behind with the amazingly horrible GNOME 3 desktop. They responded to usability complaints... let's be generous and say "dismissively." Mozilla Firefox has been doing the same. The most recent offender on my personal radar has been The GIMP image editor project, which has decided that being usable by those people -- such as yours truly -- that have been using it for 10+ years are no longer a primary concern of theirs, since they're going to target "professional graphics designers," i.e. the people who use Photoshop and who will never, ever give it up for The GIMP, no matter how much they might want to delude themselves. (GIMP has never been -- and will never be -- an alternative to Photoshop. It's an alternative to PIRATING Photoshop. The difference is subtle but important.)
There's just a systemic arrogance that, I suppose, has always been there, but it's taking a new direction in the attitude that these projects are acting like they only want "their sort" of users to use their software. Apple can pull that off because they've made marketing an art form. These guys? Not so much.
TL;DR:
Not a chance. The prevalent "My Way or the Highway" attitude was what drove most of us[footnote]Stallman's legions of frothing zombies notwithstanding[/footnote] away from MS and Apple in the first place. Windows 7 offers a better Desktop experience than Linux again, and when I have to work in Linux, I can do it in a Virtual Machine.
