The need for revisions
Given that products need to be revised every few months or so to keep them fresh and that CPU speeds are hitting brick walls and yield issues it becomes clear what apple have done here. They have launched a form factor that will appeal but specifications that the may leave mac / gaming addicts questioning the need to buy. This helps to keep demand down to a manageable level. In 6 months time, what gets revised. Maybe a small CPU speed bump (assuming that Power Macs get a bump). Definately a bigger GPU bump. Another 6 months, another GPU bump. As SJ said during the WWDC - the GPU is where the performance gains are to be made.
