OK so with all the talk about the low prices on the 2012 base, I'm just wondering if it's a worthwhile upgrade from my 2011 Base mini? It sure seems tempting to get one at around $400 or so, but would I notice the difference or should I just bite the bullet and spend more and get the 2014 mid model or even the quad 2012? I use the mini in a dual role as my HTPC server (Mini and 3 Rokus as clients) and client running Plex using HDMI and as a general duty computer doing browsing, word processing, etc. Nothing to strenuous at all. My storage is via NAS and a Thunderbolt drive so USB3 really wouldn't matter to me much.
