I'm in the market for a new system and would consider an iMac. My biggest question is if the standard 4GB is really going to be more than just sufficient for what I'd use it for. I mostly would use it for things like browsing, streaming audio/video, office-type tasks, messaging, DVD/CD playback and often multiple instances of those things at one time. Nothing too demanding, but my old 1 GB Mini wasn't always enough.... and I don't know how much more resource intensive 10.6 is than 10.4. I know I could get 8 GB in it, but $200 more for that upgrade is a bad deal. I don't want to worry about upgrading it myself or anything like that.... when the thing comes, I want it to have everything I need.
