Here is a question for those of you that make music on your PowerBooks: Is there any reason an aspiring DJ and musician such as myself should buy the current rev of the TiBook, rather than a 17" AlBook, or waiting for the updates to the 15"? I'm thinking specifically of OS9 booting capability. In other words, are there any software packages that only work on OS9 that are essential to music production? Your input would be extremely helpful as there are some deals to be had on the 15" TiBooks right now. Just a little background on myself. I'm a Windows user currently looking to switch. Ordered a dual 2.0 G5 for my home (not here yet, of course), but I need something portable that I can take to gigs as well. I currently use Cubase SX (PC), Reason, and a whole multitude of soft-synths. As a side note, it seems that Altivec fairly rocks on any music crunching tasks, and explains why Macs do so much better with multitrack effects and such than PCs do.
