I am really sold on the idea of an SSD for the OS and critical system files. The videos I've seen on the interweb have shown performance increases that are magnitudes above an incremental processor upgrade. The bottleneck in modern PC's is the fetching and moving of the data, not the processing of it. Bring on the SSD!
Would be nice for the ultimate versions to include a small one as standard though. But looking at Apples pricing of SSD's, I doubt it.SSD's have been on the imac for over a year. I expect the same option for the new ones.
