I've really gotten into adjustable monitor arms; I have 3 x 24" and a laptop stand, all on dual ergotron arms. Being able to reassign monitors on multiple systems (mba, mbp, desktop linux, system-under-test) is really nice.

I'd probably add a core 30" if I didn't already have more 24" than I needed at the time. 30" + 24" portrait (2?) is probably the sweet spot for a single desktop machine + laptop.
