I am a poised switcher waiting to (hopefully) buy a TiBook this week. Protestations about how I should wait for the 15" Aluminum PB because it will almost certainly have [insert new feature here] aside, I was wondering if I should think twice because of the firmware...or maybe I'm, terming that incorrectly: As I understand it, some of the older (beige Power Mac G3s, some iMacs) machines require some partitioning hocus pocus in order to install OS X. My assumption is that this is because of the firmware/mobo/logic board. Am I wrong here? My ultimate question/concern is whether something about the architecture of the new PBs is somehow an improvement over the TiBook's (FW800, Ultra100, etc. nonwithstanding). If the only difference between the new/old architecture is the (in)ability to boot into 9, i'm okay with that. But I don't want to miss out on some feature or not be able to upgrade to a future OS release because of this. (Yeah, I realize it will inevitably happen someday.) Again, realize I don't actually *own* an Apple yet, and all this is conjecture based on stuff I've heard/read - so if I don't have a clue, tell me so!
