Hi, I appreciate anyone taking the time to answer these questions. I'll be using this iMac for audio production with external audio hardware I already own (Firewire 400 based). I'm looking at a 21.5" iMac and hoping to spend under $1300. I'm running a 2.0 Ghz Core 2 Duo PC and it's slow and buggy even with a fresh OS. I am eligible for the Education Discount. Is the Core i3 much faster than the Core 2 Duo? Which refurb model is the best bang for the buck? Do the refurb models go on sale on Black Friday? Is Black Friday worth waiting for? Is refurb a better deal than education discount? Should I get a wired keyboard to avoid battery changes? Is the 3.06Ghz sufficient or should I jump for the 1TB drive model with 3.2Ghz or simply upgrade the hard drive only myself? (Pretty tech savy) Any other recommendations for a new iMac? Thank you!
