I use three monitors at work and I'd like to keep it that way. I like 1600x1200 + 2 x 1280x1024. One monitor for QuoteTracker, one for engineering work and one for email and web browser.
Oh. Now i understand why you need triple monitor support. Beyond notebooks, certainly. Just curious, do you use three grafic cards for this configuration?
On second thoughts, "Beyond notebooks" was premature. A pcmcia grafics card allows for a three-monitor-setup. No clue bout capabilities and affordability of those, though.
