MacPro or iMac? I'm stuck between the two, and really wish Apple offered a consumer-level tower. Right now, I have a G5 PowerMac that is about 3.5 years old. I'd been planning on getting a MacPro when the line refreshes, but a recent conversation with a friend who got a new iMac (and is really happy with it even though he's traditionally gone for towers) has me thinking that the Pro is probably a bit to "pro" for me. In short, what I use my Mac for is: serving up music to my home office, my iPod, and my AppleTv; playing World of Warcraft, Warcraft III, and Sim City 4 (and hopefully Spore if it is ever released); editing home movies and managing family photos in iLife; and converting videos with VisualHub and ffmpegX to work on my AppleTV. I know that none of these activities is especially "pro", and so the MacPro is probably overkill. What appeal to me the most about the Pro line is the multiple internal drives, and the ability to upgrade my video card if I ever want to. Further complicating my decision is the fact that I already have a 24" Apple display that is about 3 years old, and I'm not sure how long I can count on that working. (As an aside - if I got the iMac, is there a video-out port so that I could use my current display along side the iMac)? Are there any objective measures of how much faster a 2.8ghz Intel iMac would be than my 2ghz PowerPC PowerMac and how much slower than a dual 2.66mgz MacPro? Right now the only thing that is far too slow for me is video conversion. Price differential betwen the MacPro and the iMac would sure buy me a lot of external hard drive space. Please help!
