Are there any owners of 20-inch and/or 22-inch Apple Displays who can comment on the monitors, particularly in comparison to one another? I'm looking at buying a used one off eBay if I can find it, and while the 22 is initially more interesting, I'm troubled somewhat by the resolutions -- according to what I've read, the 22" does 1600 x 1024 as its native resolution. But the cheaper 20" lists 1680 x 1050 as its optimal resolution. Is that right? It doesn't sound right that a 20" would support a HIGHER resolution than a 22". Given the fact that I'm used to a 12" at 1024 x 768 and/or a 17" at 1280 x 1024, would I find the resolution on the 20" too small, or perhaps the 22" too big, like working on a 14" iBook and its big screen with too few pixels on it? Are there other factors I should be thinking about here other than pixel size between the two, because it really does sound like a 20" would be the better fit for what I want to do, and certainly lighter on the pocketbook to boot. Any guidance would be very much appreciated.
