Well as I though the 2.3GHz model was far easier to find than the 2.6GHz model. So I have an i7 Quad Core 2.3GHz model, 4GB Ram, 500 GB spindle drive, 1 Thunderbolt 1 port, 2 USB 3 ports, Ethernet port and 1 Apple display port for an external monitor.
Not quite to my specs, as I wanted to be able to run two external monitors but there are some ways around that issue. I could run a Thunderbolt monitor but I don’t have any of those and they are way too expensive anyway. I am not so sure they will ever come down to the price point of traditional monitors. So at this time I am looking at using a USB Display Link adapter to run the second monitor.
As I said not quite to my specs but at a price point where I can afford to do some fiddling around with it to see if it is possible to replace a desktop unit with a laptop. I have now packed the iMac away while I begin to use the laptop. Hopefully it will only come out for wiping of the hard drives before I on sell it (or the laptop).
Time to buy some bits and upgrade the Pro.
