My set up in March, 2003.

On the desk: Titanium PowerBook G4 1Gz
On the floor: custom-built PC running my email and web server on SUSE Linux

This sums up things nicely.

Bought myself a PowerBook G4 ;D

Accepting a 3 year old scratched and beaten PowerBook as my "new" dev machine. Especially when my personal, 4 year old one is as powerful but with double the disk space (SSD) and RAM... Then of course the new guys just joining actually do get new out of the box devices just as we're accepting that it's just not how the company works... I guess that's the bane of doing dev in a company that does resourcing as it's main focus thereby never understanding what's needed by us developers and why it is, or rather should be, different from the rest of the company.

Playing lego.com games on my family's PowerBook G4, if my memory serves me correctly. I started programming with a Lego robotics kit.
