Hey everyone, my first post here! I've lurked for some time but I'm now getting ready to take my first ever plunge into the world of Macs. I've been dreaming of a Mac for years while settling for PCs so here's hoping I won't be disappointed. (Don't expect to be.) My first two questions are simple really. For someone like me who wouldn't really call myself a power user, should I even consider a Quad-Core iMac? I will be going to college in one or two years, and could start using some more processor intensive applications then though. I'm also thinking that opting for Quad Core now would "future-proof" my iMac for a few more years and increase resale value...Someone did have a good analogy between the G4 and Intel iMacs and how what may have seemed decent back then between the two would be rubbish now. Would I see a significant improvement in performance while I'm not doing anything too intensive? My second question, what are your experiences with refurbish systems? There's a good 500 bucks to be saved by going refurb, sometimes more, and I'm just wondering if the risks are too high or if it's a good deal. I definitely don't want to end up getting a yellow screen refurb or some of the big problems I've been hearing about. Also, the refurb I'm looking at is top of the line in everything but ram (which can be added more cheaply afterward anyway) but it only has a SSD. While I've heard they are fast, how difficult would it be (if possible in the first place) to add a HDD? Honestly I think the 256gb is more than enough for me -- I rarely fill up more on my computers, and the speed would be nice, but that could change if I decide to get an Apple TV and use my iMac as a multimedia streaming center for my TVs. EDIT; Would getting an older Apple TV with a built in HDD be an option here? I suppose an external HDD could be an option if an internal one isn't possible, but what are the downsides? Last question and then I promise to shut up: I can get Applecare for refurb systems, correct? I think I read that somewhere but just double checking. Thanks!
