Exactly, a "$249 ARM Chromebook" hits bulls-eye what Chrome OS laptop should be. Developers(and other users though less likely) would not mind paying $249 for a laptop which obviously has constraints compared to its more powerful and more expensive counterparts.

Chrome Pixel looks like a powerful laptop plagued by the limitations of Chrome OS. Chrome Pixel is not going to be (in my opinion and probably Google doesn't expect it to be either) a sellout product but it highlights Google's vision of how laptops would be in coming years.
