I own a Surface. Having a touchscreen is one of those things that, for some at least, becomes a must have. For me it helps it walk the line between productivity machine and Youtube-while-cooking-dinner tablet.
Original claim: "There's no touchpad Yet... with many of the Apple technorati asking for one and saying it's a necessary next step"
Have actual "apple technoratti" asked for a touchpad? I never read one do so.
Have they asked for touchscreens? Some did, some are against.
In any case, I don't exactly see the reasoning.
iPad is criticized because it doesn't have mouse support, and the Mac is criticized because it doesn't have touch support. As if a hybrid model wont have all the problems the Surface has -- (touch not that useful when using a keyboard, and mouse-based apps not that useful with touch) --and presumably the kind of lackluster sales the Surface has compared to the iPad.
Note that while he does propose one, he does it contrary to the spirit discussed here (of getting desktop OS X parity), even adding: "Even if users expect a mouse cursor when they first see the trackpad, they’ll adjust quickly when they realize it isn’t there. If they wanted a MacBook they’d be using a MacBook. By definition anyone using an iPad is not expecting it to act like a Mac."
