First of all, performance is not all about the cpu. Powerbooks have mighty good internals and the real world performance of a Powerbook that has similar cpu than ibook is anormously better than the ibook. There's a 25-30% performance hit for ibook due to internal design (compared to similar powerbook), and Rosetta puts in another 25-30% performance hit -- so there's just no way for this rumoured ibook to be faster than current Powerbook.
What do you mean by "... due to internal design..."? Even if Apple puts in the current Pentium Ms into the iBook, at say 1.5Ghz (pretty much the slowest PM these days) it will be very compariable to the G4 1.67.
I own one of these, there is no pixie dust, no myth of the mhz myth, no nothing.. that 166mhz bus and 25W power consumption is really not cutting it in this day and age.
I don't care if George Bush uses the same PB as me to command the entire US army and edit videos of his grandkids at the same time, it is seriously a legacy processor that is starting to show its age...
How so can Apple slow down the iBook due to internal design changes?
Disregarding anything that is not natively compiled, for the most part at least the OS will be quicker, Safari will be quicker, mail will be quicker, iApplications will be quicker, Java applications will run quicker.
I don't mind a 30% penalty on a processor that is already probably as fast if not faster for the odd app that is not natively compiled for Intel.
Short of Apple deliberately crippling the CPU on those iBooks, it is seriously going to give the current PBs a good wooping.
I really urge anyone who is having second thoughts about your recent purchase to dump it on eBay asap, the bottom is going to crash out of PPC pricing.
