I was just reading an interesting article linked from www.lowendmac.com, which interestingly states what many have suspected. It wasn't only really about the power of the chips for the swtich, but many other factors we have yet to know about. It also states that the PPC was going to go through a renaissance of sorts and the 3GHZ would've made it this year. Of course the supply would've never met the demand, so Intel makes sense financially in a lot of ways especially marketing wise. Keep in mind mac hardwars sales were on the rise last year despite not having Intel. http://www.blachford.info/computer/articles/Timing_is_Everything.html There's also a mention of something that most likely won't happen, but I always wondered of Apple choosing to use to different architectures. It sounds innovative and would be the only company to do it. Especially now that UB are being coded.
