Also, if you're looking at a high-end 21" iMac... it may make more sense to just get a refurb 27" 2011 for pretty much the same price. This would give you a slightly better graphics card (with more VRAM), a bigger screen, and the ability to add your own RAM. Currently, this is pretty hard to do because they seem to be sold out often. Mainly because everyone realized that the 2012 21" are a poor value in comparison.
