OSX has plenty of annoyances, and that's what this is - an annoyance. Multi-monitor support exists, it works great - just not on the Lion-new "fullscreen mode".
I have used 4x simultaneous monitors on my MBP for years, and it's still more comfortable overall than Windows7 (YMMV - Win7's experience varies greatly on your drivers/hardware).
Apple has always had issues with window-management, it's one of those things like lock-screen that Windows still does better in some ways.

Right? Unless I'm missing something, my friends and I all use a hot corner to activate the Screen Off to be able to lock our screens when we leave our laptops since there is no Win+L or Lock equivalent. :/ I guess they just expect me to close it everytime I leave? I have lots of long running stuff that I normally don't want to stop just because I want to go to the kitchen or bathroom.
Actually, that's now resolved since Snow Leopard - there's a "sleep display" key-combo (IIRC: Ctrl-Shift-Eject) that, combined with screensaver password will do effectively Win+L.
My major issue is that sometimes it showed content before screen is unlocked (likely my displaylink device) or fails to unlock (sleep/unsleep resolves this)
