This sounds like a crazy question.  Especially, for anyone that ever used a 13 inch green screen...

But recently I started working on a 30 inch flat screen and it is AWESOME!  It is a lot like having side-by-side 15 inch monitors, except there is no physical break in the middle.  It is great to have a long task bar, since I usually have 7-10 things open at once.

The only adjustment is you can't look at the entire screen at once any more (without stepping back a few feet).  I miss seeing the new mail popups from Outlook.  BUT I can live with that!
