have you even looked at one?
a 30" at 2560 resolution is finer than a 24 at 1920, at least with the two i saw side by side. maybe i was looking at a crappy 24"?
not sure what the brand even was on the 24, but i did set up the resolution on both myself, so i am sure about that part. BTW, electronics store employees don't know shit about anything larger than a 24. they don't know what cards to use, etc. guys at best buy and circuit city were clueless.
Had to go to Fry's, and they let me set up everything myself. they didn't even watch over me!
