Wish I had a setup like that, I just have two . . .
My 15.4" widescreen laptop screen, and a rubbish HP 15" CRT (free though, so I can't really complain)
Hopefully I'm getting a 17" TFT soon though, also free . . .
And I nearly bought a touchscreen the other day, but then I thought "When am I actually going to use that?" and resisted the urge - I'm proud of myself.
