First of all, i really apologize for posting yet another "Should i but this now, oh no PB updates soon, then Macintel!!!111ONE111!!!!" post, but my situation is somewhat complicated, and this will be my first possible upgrade since switching to Macintosh. So here we go... My current Mac is a Ti PB 1ghz 512ram 60gb hd sd. Great machine, still runs great, no dead pixels, etc. The only issue is that i work with audio processing a lot, being a grad. student in music composition and all, but that is the only really strenuous thing i do with it. Some of my audio software tends to 100% my cpu, so i am looking for something with a bit more processing power. So either i am going to update my current PB by upgrading the ram to 1gig ($200) and upgrading the HD to a 80 5600 rpm(or 7200 rpm, $150-$220), or buy a new 14" iBook with my edu discount for $1154+tax (upgraded HD to 80 gigs and dropped the superdrive). I would also bump the ram to 1.5 ($140 for 1gig so-dimm from crucial), for a total of ~ $1375 (after ram and tax). My thoughts are that i will notice a large difference in speed b/t my Ti PB and the new iBook because of the difference in ram and the difference in processor speed. Any drawbacks to the iBook? Will the 1" in screen size make a difference? Will my fellow grad students make fun of me doing "serious" work on my cute, white iBook? So it is either spend $400 on my Ti PB and wait until the rev b Macintels to buy my new laptop or spend $1375 and buy the iBook now and wait until rev b or c of the Macintels to buy my next PB. Buying the iBook would also mean me selling the iMac in my sig. and maybe after using the iBook for a bit, selling my Ti PB. Any ideas on what the iMac and the TiBook would go for? I am really stuck on this decision everyone, and any help/comments are more than welcome. Thanks in advance! Edit: Also the iBook would give me airport extreme and bluetooth 2.0. AE is not that big of a deal to me, but i am working on a electronic musical instrument and it would be great to transfer the MIDI data wirelessly via bluetooth (which is possible with a certain analog switch-to-MIDI interface).
