You need to have access to and be competent on all systems.
My weapon of choice is the MacBook Pro. Pretty fast hardware. Swap in a 500gb hdd and triple (or more) boot os x, windows (xp and vista), ubuntu, bsd, etc.
Or you can get a bunch of different machines and use synergy. I found that to be most useful for testing web stuff across platforms.
