I think I'm sticking with Ubuntu.
Installed it on my laptop. Wireless worked fine out of the box, even with just the live CD.
I admit that in the end that my reason for preferring Ubuntu isn't entirely rational. Sure, in part it's
their philosophy. But I think mostly it's more like driving the same car for 10 years. You get bored of it after awhile. So when you go to buy a new car, you'll pick something a little different. That doesn't mean your new car is inherently better than what the new model of your current car would be, but it's just time for something a little different.
So far the only software I use regularly I haven't found something equivalent or near equivalent (or even better) with Linux is Adobe Acrobat Pro, but I don't really use that too often, and I'll be keeping a dual boot until harddrive space becomes a problem.
Considered Mint Linux too but didn't see much difference -- just some preinstalled codecs I'd have added anyway, and a slightly different look, and I liked Ubuntu's better.
And yeah, I'm sure I'll get sick of it soon, but it's just fun to do something different for a change. And yeah, it's a needless waste of processing and video power, but those desktop effects with the multiple workspaces and the spinning cubes/globes, just make things fresh.
Check out what my desktop looks like while spinning between workspaces:
