Here's my setup at work. 15" TiBook on the left,
blueberry indigo iMac center, and my own 12" AluBook on the right.
Man, it feels good to work at a Mac-friendly company!
Oh, and did I mention that we use a few Xserve RAIDs (among various other non-Apple hardware) in the local server room too? Yeah, we just got a couple more recently.
