Re: DougS: No it is.... No, it's not
If you like touchscreens, why did you buy a Macbook instead of a Windows laptop with touch? Whatever your reason, it seems that whatever the Mac offered was more important than the touch ability. I'd want to get off the Windows platform too if Windows 10 was my only choice...
I don't know how you used your Lenovo, but I can't imagine how touch would be of any use with my laptop. Since the screen is not hand-held, it remains in a relatively fixed position in front of you, and you have to hold your arm up to reach the screen. It's going to get fatigued pretty fast if you're doing anything more than hitting play on a media player or something like that. And that's certainly a valid use, though most people who only want that seem to go for tablets instead.
Still, what Doug wrote is still mostly true, as far as I can tell (I've never taken a survey or anything like that). Most people I've communicated with who use convertible devices only use the touchpad and not the touchscreen when it's docked. Of course, it's not literally true that NO ONE uses touch when other pointing devices are available, but for the most part, touch on a laptop or desktop is more about "gee whiz" appeal than any actual practicality.
I would never accept the UI compromises to make touch work unless touch was all I had (as with tablets that are not convertible). Look at Windows 7 vs. Windows 8.0-- the former was built for mouse and keyboard with touch as an afterthought, while the reverse is true for the latter. I'm told using Win 7 with a touchscreen is nightmarish; I would certainly expect it to be far less than optimal, given that the UI was not designed for touch. Windows 8, as we all know, was rejected by the PC market because it was similarly bad with non-touch PCs, though Windows tablet and phone users largely loved Windows 8.
Touch and mouse have different requirements, and trying to make one UI that does both is a fool's errand. The best MS could do to salvage Windows 10 would be to include two separate UIs for everything, and to select the one to use based on usage conditions and user preferences. That, though, would not be one UI for both... it would, from a UI perspective, be like bundling two separate versions of Windows together and calling it one product.
