So, for a variety of reasons and hookups I have two options: 20" iMac 2.66 with 1TB HDD, 4GB RAM for $1,109 + Tax. 24" iMac 2.66 with 1TB HDD 4GB RAM for $1,199 + Tax. That $90 is almost exactly the tax. So, what should I do? The frugal side of me says go for the 20" and get a 500GB Time Capsule and replace the HDD in that to 2TB for another $100 and some DIY, but the other side says get the extra 4" of screen (which I don't REALLY need...) So... suggestions?
