I was pretty excited to hear about this. I had always thought the low performance G4 chip in the Apple iBooks and PowerBooks was a huge minus to a otherwise interesting package. While I had hoped they would join the AMD camp the Intel based machines are interesting.
One of my coworkers pointed out that, on the day that Apple announced the x86 based Mac's, Apple stock (NASDAQ:APPL) closed at 80.86.
It must be a sign.
If Apple really wants to make personal computing interesting then OS/X needs to be available for retail purchase for installation on non-Apple hardware. 64 bit please.
