Okay, after reading through this thread, there seems to be an interesting trend. Almost everyone has beefy processors and lots of memory .... but it is all hooked up to a 19" monitor. Sure, there are people with the 27" iMacs and 30" monitors, but they sure seem a lot less than I would have guessed.

For those of you still using laptop screens, 19" monitors or even 22" monitors, have you tried something bigger? The difference in my productivity between a 30" or 2x24" monitors and the screen on my laptop is palatable. In fact, I'd go so far as to say that given all the cloud computing these days, I'd take a slow system without much memory as my local box if I could get a bigger monitor for it.
