without much fanfare apple released the macbook rev. D last week with decent bumps to the cpu (Santa Rosa), systems bus (800MHz), increased installed ram capacity (to 4G), better ventilation (larger rear port), and an "Intel GMA X3100" graphics card which uses less power and runs cooler.
GMA's (graphics media accelerator) have no on-card ram. they 'share' system ram using the bus/cpu which may impact the performance of graphics heavy applications. something to be aware of and a deal breaker for me unless proven otherwise. if anyone purchases the macbook rev. D, i would be interested in your personal experience in imovie, finalcut, photoshop etc. best...jf
