1. I actually get comparable performance with the proprietary Nvidia driver in Windows and Linux. All of these systems seem to have Nvidia chipsets. If you can't even choose your driver (at the least with jockey), I wouldn't consider buying this.
2. What would stop you from installing your own OS pair? I'd think you could do it at the very least through a network boot, and probably USB.
3. As with 3, what would stop you? Even if you're stuck with Ubuntu, changing Xsessions shouldn't be a problem. The only way this should happen to be a problem is if there is no access to a shell with root privileges. And if it that's the case, almost no serious Linux user would consider buying such an un-free system.
4. With Steam an Humble now supporting Linux, there are quite a few more choices than there were just a couple of years ago, and I'm sure we'll see more in the years to come.
