I actually couldnt find any confirmation in terms of the 70% improvement. I was trying to figure out whether it is truly a improvement ove the Series 2 processor or if they were comparing it to the Series 0. You know how apple likes to make the gains look larger than they are by comparing it to a couple generation old products.
I didn't either as I am debating a new series 3 SS, refurb stainless steel series 2.
Too many decisions!!!
