I posted this at the Apple forums but have had little response. I have several questions regarding PowerBooks and dual G5's. I know a lot of people ask similar questions but, like a lot of people, each situation is unique so I apologize if my questions are similar to others. I did some searching here and on other forums but there was nothing specific for my questions. So... I currently have a dual 2.0Ghz G5 system. I'm considering selling it and buying a PowerBook G4 15" system. What I primarily do with the G5 (and would primarily do with the PowerBook) is e-mail, web browsing, and video editing. First let me tell you that I'm thinking of picking up the 15" PowerBook with 1GB RAM. My current system has 1.5GB RAM. I'm concerned about speed for one thing. I know the G5 is a faster system but I'm wondering how MUCH faster. To give an example: for me to build a 2 hour DVD with my G5 takes approx. 3-4 hours. How fast would a PowerBook be able to do this? Now, with Tiger days away, how will this improve on system performance? I know a lot of people haven't gotten Tiger yet but I assume there are some developers or beta testers here that tested the new OS. Since Tiger is a 64-bit OS does it drastically increase speed performance on a G5? How is the speed increase on the 32-bit PowerBook? I assume people will mention that it depends on if you need to be mobile. Right now it's not a necessity to be mobile but something that could become beneficial in the near future. Also, I'm moving soon and with a PC and a G5 the two systems take up quite a bit of room. I'd like to reduce the amount of space taken up by my computers. Currently the projects I generally edit are weddings, bar/bat mitzvahs, music videos, short films... that sort of thing. Nothing commercial where the product needs to be turned around within a few hours. So, can anyone give me there thoughts and recommendations? Any advice is greatly appreciated. Thank you.
