I went for the 15" having been dead set on the 17" for months. It appears they intentionally gimped the bigger machine, removing any reason to buy it other than a slightly larger screen. I mean, for the cheaper price, you can get a faster, lighter 15" with identical specs other than a smaller high res screen. Before, it was a bigger battery, the screen was denser, and it was just as fast as the high end 15". And the cost difference was smaller!
