I'm new to the boards but I figured this was the best place to ask the question. I recently purchased Jaguar (for only $20 at my school... we have a great software licensing deal for students and faculty). I am mulling over whether or not to upgrade because I am afraid that it will make my computer worse instead of better. I currenly have a PowerMac G4 466mhz with 769MB of RAM (and I just ordered another 512MB) and a 30GB hard drive. I've been running OS 9.2 for quite some time now. It's not perfect but works okay most of the time. I have trouble with the computer freezing up and giving me little problems. Things that I can't seem to get rid of. I was thinking that upgrading to Jaguar might make things better and more stable. I purchased my G4 last year, when the first release of OS X came out. So I have both OS 9.2 and OS 10.0.3 on my computer (they were pre-installed). I tried using OS X the other day and it was sloooooooow. The computer started up okay, and OS X started up fine, but it took forever to load the "classic mode". And the programs seemed a little slower than on OS 9. This worried me. Does Jaguar fix problems with the earlier version of OS X? Is it any faster? Does it work with "classic" better? My computer isn't the fastest in the world and I do not want to make it any slower than it already is. I also don't want to deal with the computer freezing or crashing as it moves back and forth between the OS X applications and "classic" applications, or while I"m surfing the web or something. Then there's the whole issue of how Jaguar would interact with my printer, scanner, and DSL modem. Hell, I don't even know if OS X would interfere with my DSL service. I'm sorry to bug people about my concerns but I really don't want to make a mistake. I'd love to have the money to just buy a brand new G4 with dual processors and Jaguar pre-installed, but I don't have money to fork over for a new computer when I just bought this one last year.
