By the time you have a giant 6" trackpad, then a touchscreen just absolutely makes more sense, but oh, yeah, right, Apple insists on being a decade+ behind the times on laptop hardware features while insisting they're better.
Their position is if you want to fing on something, fing on an iPad.
If you want to type, point and gesture, get a MacBook.
I'm very ok with that and personally satisfied that Apple didn't jump on that bandwagon.
