Have you ever tried using touch screen on windows as a developer? I just don't understand how people can list it as a benefit, windows interface especially in any apps for developers is horrible for touch use, and don't forget that in order for you to touch the screen you have to raise your hand , how many times a day can you do that without your shoulders being sore?
The thing I applaud Apple for is standing (at least here) the ground and not going with a touch screen for laptops, I think having a touchscreen in a laptop is a horrendous and useless idea, touch screens should only be on the object where you already lay your arms on, like keyboard in this case with Apple, having a touch screen 5 feet away from your hands will make you not want to use it, and that's not even considering OS your which is not meant for that
