Apple iMac review (24-inch, 3.06GHz)

Apple recently updated its iMac line, updating the components without touching the brushed-aluminum-and-glass design that it introduced last August. As in the past, Apple sells four iMac models--two 20-inch models and two 24-inch models--each of which allows for some degree of customization. The four default models keep their previous price points while moving to Intel Penryn processors, which offer higher clockspeeds and more L2 cache and operate on a faster 1066MHz frontside bus. Please see our full review of the 2.8GHz, 24-inch iMac for more information, including performance analysis.

Of the two 20-inch models, the biggest change with this update comes with the higher-end $1,499 model, which now offers 2GB of memory--double the amount offered by the previous model at that price point. All iMac models now use 800MHz DDR2 SDRAM--faster than the 667MHz memory from previous-generation iMacs. Aside from the new Penryn processors and memory differences noted here, the rest of the components remain unchanged from the previous generation 20-inch iMacs.
