Last year, at the launch of Apple Computer's powerful PowerMac G5 systems, Apple CEO Steve Jobs promised that the company would reach 3.0GHz by the end of June 2004. This week, the company admitted that it had fallen short of that goal, as it just shipped dual-processor 1.8GHz and 2.0GHz PowerMac G5 systems and won't ship a dual-processor 2.5GHz model—complete with liquid cooling—until next month at the earliest. The liquid cooling requirement on the 2.5GHz chips says it all: The G5 processor simply runs too hot for traditional cooling, and we're unlikely to see 3.0GHz on that platform anytime soon. This is the second time in 2 months that a Jobs pronouncement was proven false: Last year, he promised more than 100 million iTunes downloads by the store's 1-year anniversary, but the company was able to garner only 50 million sales, despite a high profile Pepsi campaign that tried to give away 100 million songs but fell miserably short
