Apple is doing this because P is further down the alphabet then G. Also, 7 is higher than 5. Thus they are able to jump from a G5 all the way to a P7 (Pentium 786), P + 7 is further down the line thus a big boost in performance. Also they will not loose their PPC because of the following mathematical formula.
Dual core Pentium or two P's (PP) and still works with x86 Cisc (C)= PP + C=PPC
Got it everyone
