I was looking forward to the 21.5" retina iMac, but I'm not satisfied with the internals - no Skylake, thus lackluster GPU with no dGPU option - not to mention the base hard drive. I'm going to wait for the next iteration or a new mini that knocks my socks off. But, in the mean time, I'm going to put an SSD in my 2009 Mac Miini running Snow Leopard. It has 2x2GB memory now, and I'm debating whether to bump that to 2x4GB while I'm dusting things off in there. It's mostly just an internet terminal, but I've forgotten how to interpret Activity Monitor info in my old age. It's showiing 1.03GB free right now, with page ins: 1.21GB, page outs: 899MB, and swap used: 270MB. Looks good to me, but what do I know? I'm asking because I may have to wait another year with this set-up but what's the sense of spending more than I have to just to tide me over?
