I am a big fan of the Lenovo ThinkPad line, at least the T and P series which have great build quality. X1 Carbon also have a fanbase but I haven't used one. I think the X1 is a lighter model where you lose some power and features for less weight, like a MacBook Air. Some of the Yoga models look enticing but I don't know much about them. Other series are not as well built and I wouldn't consider them. Custom builds have crazy long lead times nowadays, and many stock models are in short supply.
A friend has a touchscreen that took me a while to get used to. I would try to point at things to explain and select things when I didn't want to. Once I got a touchscreen and got used to it, I think it's great.
I have four 14" T series, all with touchscreen. My work laptops are 14" T series without touchscreen and I miss the touch. I also have a 17" P series. If touchscreen was available on that with 4K, I would have got it. I did consider a Dell XPS 17 to have a touchscreen, but that would have cost about a thousand more than the P17.
If you can go through Perks at Work, it's the best Lenovo pricing I've seen, at least for me. Lenovo is our current corporate supplier which might help.
