What has me most frustrated is that the best "bargain" is the base 16". The bargain part being that you can get the factory-configured specs at serious discounts, down to $300 off at around $2100, and you get serious beef for the buck.
When in fact I too would really prefer a 13" form factor. But the thermal compromises are extremely frustrating. By the time you got a solid, updated 13", you're at $1800, which is again $300 away from two extra cores and discrete graphics. And a bigger screen, which I wouldn't even want…
