iMac
The not so humble iMac has come a long way, and now for photographers it has taken another leap with revision 3 of the 21.5" and 27" models. Whilst we still maintain that the iMac is a "Pro-sumer" machine (cross between professional and consumer), the new i5 and i7 Quad-Core processors in the 27 inch model really put a dint in the processing time. Our Capture One processing speed test rated the previous models in the same zone as the 2008 Mac Pro 8-core 2.8GHz, we'll have to wait and see what these new iMacs can do!
The 27 inch give us nearly the same number of pixels as a 30" display (2560 x 1440 vs 2560 x 1600). The colour gamut is pretty good, but it is not recommended as a high-end retouching workstation - you really need an Eizo ColorEdge LCD display for that.
There is a little bonus with the 27 inch model, the iMac can also be used as a second display! That means if you have an iMac as a capture machine, when you are not capturing, you can connect it to your Mac Pro or MacBook Pro as a second display - you just need the right cable (we sell them too!).

Ideal iMac model for a photographer
Below is a summary of what we'd suggest is a possible spec for a busy photographer:
- 27-inch display with 2560-by-1440 resolution
- Quad-core Intel Core i7 processor 3.4GHz
- 16GB of 1333MHz DDR3 SDRAM (or 12GB if this is a stretch)
- 256GB Solid State drive with a 1TB or 2TB Serial SATA drive
- ATI Radeon HD 6970M with 2GB graphics processor
- ... and of course AppleCare Protection Plan to keep it under warranty for 3 years
Please remember that we would alway suggest a mac with a specific graphic moinitor for those colour critical jobs.

Of course, just as with previous high-speed interfaces, performance of each connected device will often be much lower thanks to the limitations of the device itself; for example, most SATA hard drives top out at 3Gbps, and even SATA 3.0 drives are limited to a theoretical 6Gbps. Similarly, an older, slower device placed in the middle of the chain can—if not connected properly—cripple throughput for higher-speed devices connected after it.
