Holy crap what a disappointment. I've been jonesing for an upgrade for about 6 months now (my current desktop is a Mac Mini 2009) and was eagerly awaiting an updated mini.
So the new mini has a new Ivy Bridge cpu. Whoop-dee-doo.
It only has one Thunderbolt port but at least it does have USB 3.
It only has Intel 4000 graphics. That's a crappy gpu that uses main memory. The reason I wanted a newer mini was so I could play a video game made in the last 5 years. As far as video games go, this mini is worse than the last one and only marginally better than my 3 year old one!
Looks like it's Hackintosh for me because this mini sucks.
