Personally, I can see a purpose for this type of computer even if I don't think they are a practical choice. They would be great for someone that rarely plugs stuff into their laptop and values light weight with a beautiful (small) screen over everything else. I am personally a fan of the 15 inch MBP and prefer an iPad for ultra-portability, so I won't be getting one. I do like that space grey, though. Also, I am sure we will eventually see docks for USB-C that will make it easy to plug in one cable to get video out, power, USB inputs, etc.
Needless to say, I could change my mind if there is a price drop that makes it easier to rationalize the purchase, but right now, I am going to sit it out. If somehow the app developers come up with something so cool that the item moves up in my view from the slight interest scale to very interested scale, I will let you know. I just can't see how that will happen in the near future. As with the MacBook, the price is higher than I would want to pay for this type of product at this point. I am not saying it is overpriced because Apple bases their prices on margins that make it worthwhile for them and based on what they think people will pay to satisfy their targeted units to be sold. If it doesn't sell well at this price, I would not be surprised by a price drop. However, to be honest, I think it will sell quite well....of course, the iPad sells quite well unless you compare to prior numbers, so if people think it will sell like an iPhone, I think they will be extremely disappointed (or happy if they are one of the many trolls that I see every time an Apple product is mentioned).
All in all, I think Apple is still making some very interesting products. A whole lot of people wanted thinner with a better screen than you can get on an Air and now they have it. Many iPhone users wanted a "smart" watch from Apple and they will have that now, too. All in all, I think Apple still has a knack for creating great looking devices that people want. I am just curious how much people are willing to pay for the privilege....
not that I am complaining.
