I need to buy a new 12" Powerbook between now and the end of August or so. Does anyone know if there is any kind of midstream boost in performance imminent? I purchased my last one a few days before the processors were boosted from 867Mhz to 1Ghz. Fortunately Apple ran out of the old inventory and just delayed my order for a few days until the new ones were ready to ship, but if I'd ordered a week earlier, I really would have been kicking myself. Am I safe to order this week, or should I wait a few days?
