This CNet article talks about a revamped StrongArm architecture coming from Intel:
The XScale architecture offers performance roughly 20 times the Dragonball and uses less power, said MicroDesign resources analyst Peter Glaskowsky. The chip architecture also is able to shift performance on the fly, throttling up for multimedia programs and conserving power when running a calendar or memo pad.
The result is a handheld capable of running video but still able to run on off-the-shelf batteries, analysts said.
StrongARM, of course, was utilized in the last incarnation of the Apple Newton. Apple's participation in the PDA Market is still notably absent.
