Well I have only had my mac for like 20 days (a refurb 15inch PB with superdrive). I lucked out when I got my mac it just happened to have a a single 512mb dim, so I bought another one, and WHAM I have a nice 1Gb of ram right now. Since I bought a refurb, I only paid $1999 dollars for the mac and a $239 for apple care. (edu discount there). I figured I saved about $400 on buying this older mac, I think I did pretty well. I could see where 4x drive would come in handy for burning the DVD's, but lets face facts, if your using imovie then shifting it over to idvd, the built time is the biggest time sucker, so burning would take 15 minutes instead of 30... I'll keep my 400 thank you very much. Not to mention I got to do movie stuff for my nephews baptism, truly pricless =) . The video card upgrade would have been nice, but neither laptop is going to be a Doom III FPS machine. The CPU update, sure that would have been nice, but I am pretty sure that when I was converting my imovie to idvd that was mostly HD spinning time. Now for those of you that waited congrads, your machine is gonna be slighty faster than mine! You gonna love it as much as I do, for those of you that where waiting becuase they where sick of 2 yr old technology in the bus, wel guess what DOH, such is life. Your going to have to wait till next year to get a PB G5. The next Mac I buy will be a PB G5 Generation 2 refurb. (about 2 yrs from now) Apple please continue to put time into getting apps to run fast on both the G4 and the G5... PLEASE!!! What ever you all get, I hope your happy with it!
