Works on my laptops with no problems
I have xubuntu on an old 2003 pentium M lappie, then ubuntu 12.10 on a 2007 core duo one and on a 2012 i5 ivy bridge and it works on all of them.
I can't say they're without issues. One of the things i've encountered is that Ubuntu tends to have issues if i set it to sleep or even shut off while running on an external monitor, and then i wake itup/turn it on on the integrated display, and it's really random when it will work or not. Also on the newer unit i haven't had the time to toy around with bumblebee in order to get the nvidia card to be switchable, so i've been running on the intel4000 and honestly i'm not looking forward to that mess, but who knows it may turn out ok.
Asides from that, the only times i boot to win7 are when i need visual studio, premiere, illustrator or photoshop. I guess i could always take the time to learn similar software for linux, but i don't think i'll be able to find the time in the foreseeable future. I also need to test running Maya on linux, so far i've kept it on windows only.
But for my main usage, which is netbeans/lamp, it's been fantastic so i only really hit win7 once or twice a week maybe.
