Apple seems to be targetting a whole different sector with this technology. See Cringley's take on this (http://www.cringely.com/2011/02/attack-of-the-minis/) about how this technology could go into data centers. Interesting move by Apple.
Oh, that's just Crazy Bob talking. If that had really been Apple's strategy, they wouldn't have alienated so many customers in the way they killed the xServe line last year. If they had really wanted to keep their toe-hold in that market, they wouldn't have said, "Let them eat mini Macs." I think it's simply the case that Apple's signature advantages in the consumer space don't translate into a 1U world, and they recognized that.
A lot of people keep parroting Google's famous "fail quickly" model of encouraging innovation. But they seem to forget another well known fact: Apart from their core search product, Google has not produced another successful product. I think the two issues are related and a blind acceptance of Google's philosophy might be more harmful than good. Especially if your company does not have the kind of cash reserves that Google has.
