I'm about to buy the 21.5 inch imac. Does anyone know which monitor is best to use as a second monitor? I've done a bit of research and apparently dell makes one that's close to the same quality.
There's also the option of buying an older 24 inch mac display. Anyone know if the casing is exactly the same size as the 21.5 inch? The resolution width on both of them is 1920 but the 24 is a tiny bit higher but doesn't have that extra space at the bottom.
