How well does it run non-Ubuntu distros? I only run Debian these days — been burnt too many times by Ubuntu.
That in-and-of-itself is a pretty impressive investment to me, but I would probably take it off and put arch on it. Honestly I am not too worried, it seems like I can actually call them for support/file bugs/ask for technical help if I actually came across an issue -- surely someone over there knows something if they want to maintain their own distro.
It's the first Linux distro that I've been able to run full-time, after trying the main Ubuntu distro for 6+ years with VMs and dual-booting.
Beyond its stability and compatibility with Nvidia hardware, its design is pretty and touch-friendly.
I'm tired of the stuff Apple pulls, so would be nice to see a good/supported linux distro for hardware. I've been bitten too many times trying to maintain Linux on a primary desktop/laptop (hackintosh has been easier for me).
