It has been a long time since Apple released the iPhone, so it's easy to forget the game Apple has played with the high-end device market. When the iPhone first came out, it was ridiculously expensive. This led to Steve Ballmer's infamous quote that it was too expensive, and no one would ever buy it. To a certain degree, that was actually true. Apple only sold 6 million 1st generation iPhones over 5 quarters. These are the kinds of sales that Windows Phone 7 had in its first year or two, but for some reason everyone complains about it having "no market share". But that's another blog post for another time.
Then, something amazing happened. The iPhone 2 launched in the 6th quarter of availablility, and in that one quarter, they had more sales than the entire 5 quarters combined. Essentially, everyone that had ever bought an iPhone 1 upgraded immediately. From there, sales increased significantly. As the iPhone got more and more customers, the notion of paying so much for a premium product became easier to stomach, for one simple reason: Every year, the previous generation got a price drop, while the new one stayed the same price. This was initially a brilliant strategy on their part, because very year the value for the price increased substantially in a way that was readily apparent. That has been a tough act to follow lately for Apple, even though that hasn't appeared to affect sales.
Taken in the context of Surface vs Surface 2, this is readily apparent. USB3 instead of USB2. 72 graphics cores instead of 12. 1080p screen instead of 720p. 4x the processing power. All for the same price you paid (or would have paid) before. That's why Microsoft dropped the price a few months before launch: in anticipation of units coming out at the same price (which actually turned out to be $50 cheaper), Microsoft dropped the price of the Surface RT by $150 and saw a significant uptick in sales.
For $449, there is HUGE value in the Surface 2, ESPECIALLY running Windows RT 8.1. Same for the $899 Surface Pro, but not quite to the same extent due to the more marginal improvements.
So, you might complain that the prices are high, but high prices = higher margins = more room for sales + more revenue to further innovate. Price it lower and you get, the same crap the PC market has been doing for the last decade. The Surface does not need a race to the bottom. That market is already covered.
