Keep buying Apple laptops, got it. I know that a large number of people keep asking for laptop with touchscreen, but this is one design decision where I whole heartedly with Apple. Touchscreen on laptops make no sense. The use case for a touchscreen is significantly different from a laptop that it makes sense to have two classes of devices.
Then again, I don't really get the large number of iPads sold either. It seems like an extremely niche devices which would only find a use case in certain types of industry.
I installed OS X on my old Asus Zenbook and the touchscreen still functioned... but yeah not once did I ever think "wow I want to apply my fingers to my laptop screen instead of using the large precise touch surface within easier reach" besides for novelty
Apple could let customers launch iPad apps on their Macs and use a touchscreen. But they don't, because they'd rather sell you two devices. It's silly, artificial market segmentation.
