Further to my reply, it almost looks like Apple designed the MP to read nice on the web page...I mean 9.9" tall, 6.6" diam, 11lbs weight. Don't tell me that is some huge coincidence. So having come up with the marketing spiel, the engineers had to go away and make the damn thing fit, TDP or no TDP.
I'm all for new thinking but not at the expense of performance or other practical factors. Sure its a workstation (it has workstation CPU) but as others have mentioned, it's really a big souped up macMini.
I thought that until I had one to prep for a client for about six hours. When UPS collected it I couldn't compare it to any other PC I've ever used since 1988. Maybe the cube perhaps the most but at the highest TDP I could push it was outrageously quick yet almost utterly silent when it was no more than two and a half feet from my ear on the desk.
Surreal and worthy of the tag of revolutionary in personal computer design. I thought Apple were talking BS at launch I'm happy to be wrong! Unfortunately I can't afford one!
