My first professional level Apple computer was a Power Mac G4 that I purchased new in 1999 for $6000. It had a 300-megahertz processor, 64-megabytes of RAM, 10-Gigabytes of storage and it weighed 13-kilograms. Eight years later Apple released its first iPhone; it had a 620 MHz processor, 128MBs of RAM, 16GBs of storage and it weighed just 135 grams! It was a salient reminder of how fast, expensive computers can become slow, expensive computers.
For this reason, a lot of photographers over the past decade or so have chosen to use iMac computers; they have better performance than the diminutive Mac Mini (introduced in 2005), while costing a third of the price
