Hello, I'm in the market for a new desktop. We currently have a 2006 imac Core 2 Duo that is quite slow, as you might imagine. We use our computer to do pretty basic tasks (streaming, surfing, iphoto, word processing and garageband) and want a screen larger than 21.5". The 27" imacs are a little outside of our price range, so I thought the mini could be a good fit. I plan on upgrading the RAM to 8 or 16 and hard drive to a SSD. My questions are these: --I've read that lots of folks prefer the 2012 quad-core; I can find those on ebay with the specs I want at an okay price, but is it worth it to forgo the warranty and buy a 3-year old machine? I'd like to not have to buy a new one if a new OS renders the 2012 not upgradeable. --Considering our usage, is there anything we'd be missing out on in the step down from imac to mini? --In the 2014 lineup, I see a $300 difference between the mid and high models, but the only upgrade I see is a .2GHz processor bump. Am I missing something more significant?
