You can say goodbye to the old 20-inch iMac G5. Apple has dropped the 20-inch model from its online stores in the UK, Europe and Japan, though the machine remains on sale in the US. At least for a while, that is.

The iMac G5 was replaced in January at Macworld Expo with a new model that uses the Intel Core Duo processor. The Intel version of the iMac uses a very different processor, but maintains the same exterior as the G5 model it replaces.

The 20-inch G5 iMac has the following configuration: 2.1GHz G5 processor, 512MB RAM, a 250GB hard drive, 8x SuperDrive, Apple Remote, Front Row, built-in iSight camera and more.

It seems that the company focuses now to the iBook and the Power Mac G5 - both likely to be transformed into Intel-based MacBook and Mac Pro. Speculation points to 1 April - the date of Apple's 30th birthday - for a MacBook announcement, but the high-end desktop isn't expected to be replaced until Intel ships its 64-bit 'Conroe' processor in Q3.

That transition will leave Apple with only its Xserve rackmountable unit to replace, for which Apple may be waiting for Intel's next-generation processor architecture with its emphasis on maximum performance and minimum power consumption.
