Help me decide. Id like to spend under $1500, which would include AppleCare. No gamers in the family, but we do a bit of photo editing (very basic using elements, not photoshop). Kids use it for homework (ie Office) Do I buy a refurbished 27 iMac with only 4GB ram for $1359 or get a new 21 base model with essentially the same processor, hard drive, and graphics for $1299? My assumption here is they are essentially the same. Is that true statement? I dont need a 27 monitor but it is nice. I do think I would miss not having an optical drive so thats another cost to consider. Or do I forget the iMac altogether and get a decent tower/monitor and learn windows 8? I hate making decisions.
