I have a Dell Laptop also 15.4'' but you can see the great lengths apple has made to make it really small. Just a comparison to show how thin it actually is. Keep in mind the dell is not that old, about a year and a half old, that's all. That's not that old for such a difference.
Thin Client Ubuntu 9.10 with LXDE over LTSP on old Toshiba laptop (TFTP, PXE) Sound works, I/O works. Server spec: Celeron 2ghz, 256mb ram, almost 1TB of storage
