I have the current Mac mini, the quad core i7, and is a brilliant little machine. I managed to get it to play 10 full hd (1080/24p) videos at once in QuickTime player and they played flawlessly. I use mine as a media server, with 8TB of external hard drives plugged in over usb3. It can transcode and stream to my iPhone, iPad, smart TV and mt iMac all at the same time with no issues and for encoding videos it's plenty fast enough for me. I too would love a Mac Pro but if I had that kind of money going spare and spent it on a computer, I'm pretty sure I'd be divorced rather quickly, as I'm not a pro and don't have a need for that kind of powerhouse for what I do with it. If Apple were to bring back a version with a ati or nvidia gpu as well as the iris pro graphics I might consider replacing my iMac with one. But at the moment I like the dedicated GPU on my iMac for games
i can testify to this as well. the i7 mini with an ssd is fantastically fast..
