I use a 13" macbook air with 4gb of ram. When I'm at home, I hook it up to a Dell 30" lcd with an old school MS Natural Keyboard and an Evoluent Vertical Mouse.

13" macbook air with 4gb ram...no extra monitor/keyboar/mouse.

I have a dual 27" screen 8 core, 8gb PC 2.5 feet from me which is great at collecting dust.

Thinkpad T410s running Arch and Gnome 3. Switched over from a 3-monitor desktop setup a couple of months back and haven't really looked back. I'm finding it easier to enter "flow" on a 14" screen than with 4000 square pixels of peripheral noise, and it's nice not feeling chained down to one particular location.

If you're not an OSX fanatic, most of the Thinkpads are great machines to hack on.

Also running a T410, + Ubuntu and Gnome 2. Works for me (mostly Python and a bit of C).
