Yep. We have several in our library at school. They are really nice.
I especially like the fact that they accept Latitude/Inspiron modular bay devices, so you can just hot swap a DVD, CDRW, HD, ZIP or even a floppy.
My boss was going to get one for his new computer, but he wanted multimonitor support, and this machine (actually SX-270 is the new one now) can only support 1. Also, it doesn't have any PCI expansion slots, not even 1 low-profile one. But on the other hand, I think it looks cool and was designed nicely.
