That's just getting ridiculous. I know phones are getting more and more powerful, but that's full on laptop money right there... and not even cheaper PC laptops, the MacBook Air starts at $1,499. Hell, even the 13" MacBook Pro starts at $1,899. That really is getting waaaay too close for comfort. While Apple products have never been cheap, they have at least been somewhat affordable... The Apple of late is becoming more and more of a niche product for the well off.
Now I'm going into total fantasy land now, but at that price, I want more from my phone. Given phones are getting more and more powerful and gaining more and more storage (they really are rivalling laptops in both regards) it would be awesome if your phone was able to act as your desktop.
Theoretically, it has the power to run OSX. Imagine if the iPhone Pro worked as a phone like right now, but when "docked" it allowed you to boot into OSX and do your real work. Power can be supplied by the dock, an external screen, keyboard and mouse could be used and life could be grand. It reduces syncing (since it's all in one place) and allows for greater productivity. A laptop shell that you could dock the phone into would give portable people that option too.
Now this concept isn't new, it's been done or considered a few times in the past, for example:
It's never taken off but then it's never had a company like Apple behind it. I also understand that they would rather sell you a phone, iPad and MacBook than an all in one device... but I can dream.
