I simply can't say 0%, but 30% is a bit high...I think 10% is closer to the truth. Look- the penyrns are going to need a new motherboard to get the most of of them...it won't be ready until mid 2008...apple just completed a shift across the consumer line to santa rosa...apple also does not mind being behind the curve and tends to ignore incremental upgrades. I just doubt they intend to have Santa Rosa be a 7 mo cycle. They want to get more life out of it than that.
