I've been wanting to get a new iMac for ages now. I currently have a 1 GHz PowerPC G4 iMac with 1 GB of RAM. It's been good to me these past seven years, but I need something more powerful as I'm starting work on a documentary series soon and my computer is showing it's age as it struggles to keep up with videos. My main question is this: I plan to get the 24-inch 3.06 GHz Intel Core 2 Duo iMac (the current top of the line iMac), but should I wait until Snow Leopard is released or just get it now? Some are saying Snow Leopard might be out in the Fall now, which is too long of a wait, but June would work. The other dilemma is that there are talks of a Quad Processor for the iMac to be released later this year. How big of a performance increase will there be with the Quad vs. the Duo I'm interested in? Basically in short, if I get the new iMac today, how much will kick myself for not waiting until later this year? How big of a pain would it be to upgrade from 10.5 to 10.6? I've upgraded my iMac from 10.2 to 10.4, but when I did that, I opted for the reformat and started from scratch. I also have some questions about transferring stuff from an old Mac to a new one. I have an iPod Touch and I've bought several apps for it. How would I go about transferring all of my iTunes stuff, music library's included, to a new Mac? I kind of like keeping track of my play counts. Oh, and how would I transfer my iCal events and Safari and Firefox bookmarks? Anyway, I think that's all of my questions. Thank you in advance to anyone who offers his or her advice.
