From the perspective of someone with a touchscreen windows device, I agree. I rarely used the touchscreen not because it wasnt useful, but because it was unwieldy on windows.

I bought a 2 in 1 and the experience is much better, simply because i can detach the keyboard and use it as a massive tablet. its not as fluid as an ipad, but most of the time its simply mildly annoying to get to the app/browser i want, then I scroll and tap the same way I would on an Ipad. On my regular touchscreen laptop, I have to lift my fingers to use the interface, which simply adds delay for... the ability to scroll a pdf, afaik.

All this to say simply shoehorning touch on a mac is a pretty bad idea simply because the hardware, in its current iteration, is not there. I wonder if they'll release a "macbook touch" thats more akin to a surface for their touch interface.
