I wonder why it is not easy anymore to find a 15 inch laptop with resolution above 1366x768. Right now I am using a 4 years old laptop with 15 inch matte screen and 1680x1050 resolution which for me are the perfect specs for laptop regarding screen. They dont the sell these specs anymore. It seems they abandoned big resolutions at 15 inches, and to get more than 1366x768 you have to go at 17 inches. Maybe there is an exception or two, but in previous years, there were a lot of models featuring 1400x1050 or 1680x1050 at 15 inches. Anyone knows why?
