I can't imagine shelling out near a $1,000+ for this thing (lets price in the keyboard and other accessories) when I can get a proper Macbook or Surface Pro, both which are much more capable. I imagine this will become the next hot executive toy (I need my twitter and my exchange mail up at the same time, nerds!). It'll sell in predictable low numbers and then one day mysteriously disappear from the Apple webpage with no fanfare.
I feel Apple has painted itself in a corner here. It never bonded OSX and iOS and carefully made them separate products. This probably made sense 5-6 years ago, but unified devices are now practical and affordable. I suspect Apple has a unified OS ready to go soon and is just buying time with this "Pro" to seem competitive. I can't imagine the status quo lasting. What exactly does a mobile OS get me, especially when it needs hardware and RAM on the level of a desktop OS not too long ago? Trying to "keep it simple" is what got Nokia and Blackberry killed. I fear that this industry is destined to just re-invent the desktop, but with sexier devices, in the end.
I'm not one to underestimate Apple, but the past couple years have been underwhelming. Even their much hyped watch is a fairly milquetoast design with a poor value proposition. Or the mobile game has simply matured and there are no more big ideas in this space. Are we at the "gimmicks and minor refinements" stage of this technology?
