I recently purchased a 2011 Mac mini. Great machine, and I do miss having a laptop, but I think I'm going to stick with a desktop, at least for a while. It does need some upgraded RAM, and I'm also considering adding a larger HDD. My question is, is it worth trying to upgrade to a 2012 before doing all this, since the RAM's a bit different. AFAIK, all I'd get is USB 3.0, and the only peripheral I have is my Time Machine disk. Other than that, a bit of a speed boost. I plan on doing some video editing later in the future and I'm sure the 2011 can handle that fine. I may even end up doing it on my Power Mac. The main reason I'm thinking of all this is I had kept trying to get a refurbished from Apple, and right after I pulled the trigger on the 2011 the refurb came up, then I saw a few 2012s on here for sale for just a bit more. But I guess that is life.
