I want to get a Mac so I can play around with Apple's development tools (for Mac OS and maybe also for iPhone). My current G3 is far too old to run Leopard and XCode. This will be a short-term solution until the Nehalem Mac Pros come out. I've seen some first generation Intel iMacs out there for a good price... will that be powerful enough to run Xcode and also use as a primary machine (iTunes, iPhoto, etc.) until the new Mac Pro is released? The iMacs I've seen are 1.83 Ghz Core Duos (not Core 2 Duo). I figure I could buy one for around $500, maybe even hook it up to my 22" display to get two desktops, and then sell it early next year for a few hundred. Does this sound reasonable? Thanks!
