I'm quite comfortable using it. This notebook is actually an Ubuntu-preinstalled Dell. To be honest though, my computing needs rarely exceed browsing, instant messaging, and photo editing/management, so I'm really not dependent on any applications that aren't available on Ubuntu. Any engineering coursework can be done at the workstations at school.
As CD said, it's a very old picture.
Switched to a fairly new one, though it's been a little tough finding the right one. But I can't help but find her smile gorgeous.
