Mac rumour site ThinkSecret heard a new Apple iMac may be launched in August. This revision will be only two inches thick and will feature a brushed aluminum enclosure:
The elegant new enclosure will somewhat resemble the current white iMac but is said to feature a shorter space below the actual display, where most of the internals are housed.
It was exactly 10 months ago today that Apple introduced the current iMac—which in and of itself represented only a minor speed bump from the first-generation Intel iMac, which debuted in January 2006—marking an unusually long gap between revisions. Sources originally expected the iMac upgrade to appear in June; it is unclear whether the change in date was a result of misinformation or revision to the product's roadmap.
The new iMac will be based on the Intel Santa Rosa platform and will only be available in 20" and 24" varieties.
