Agreed, I've got an Aura 15 as well a few years ago, and I consider it a good buy price/performance wise.
I had originally ordered a different, slightly more expensive model, and had no trouble at all with customer service to send it back in exchange for the Aura and a refund, which impressed me very positively.
I run Debian on the laptop and had no trouble with it.
On the plus side they really do support Linux, they provide a kernel module and control center app to control things like keyboard leds and power profiles, which does a good job. I find this quite good for a small company like Tuxedo.
I'm happy with my laptop and will consider Tuxedo again next time I need a computer, but I definitely advise to look at reviews beforehand.
