I think its a niche product, given the following factors.
The price is relatively high for a product that is aimed at the majority of consumers. Given the high price its lacking a number of basic elements that would appeal to the majority of consumers, including ports.
It is a laptop aimed at those people who want an additional computer and have fairly high mobility needs, i.e., road warriors.
Apple had to make a number of sacrifices in designing this laptop as thin and small as possible, could that with its high price, means its not for everyone.
The higher price is temporary. It will be 999 before we know it.
I think you overestimate ports. Most people probably never use one, and if they do it's sparingly. I know a lot of people on here use their laptop most of the time at a desk with 5 wires hanging out of it, but that's a tiny percentage of people.
Correct, some think its a great computer, others do not.
My point is that the design choices apple made limits its mass appeal, and couple that with the premium price, means its a niche product.
People said the same thing about dropping the optical disk drive in the MBP. A couple years later and you don't hear a peep. No one cares anymore. I suspect the same with be the case with the lack of ports.
