But yeah I'm getting sold more and more on the touch screen, honestly. I think gestures and such have the potential to be neat, and could optimize my workflow.
Being able to move and resize windowed stuff in i3, something I have bound to mouse keys at the moment, would be really neat with a touch screen. Makes the desktop seem tactile and real. It is a pain to move them with key presses, so I usually move my hand to the mouse anyhow.
Gestures, like some tap or something to move a window out of the scratchpad, and back to tiling mode or whatever. Neat. Though the keyboard combination I use now would probably be faster.
In addition, as Someone1234 pointed out, native touch events would be really nice to have when doing web dev. I for one constantly use the Chrome mobile emulator. Native would be better.
I dislike most laptop manufacturers of this day, because they all either:
* Only make touch-screens in 4K
* Don't let you upgrade your RAM.
* Only sell with Windows bundled. Not paying for Windows, no thanks
Dell satisfied only one of those criteria. They are very high in my book. In fact, I am using one of their 4K monitors right now.
I agree with you on System76 though. I am in the process of being a Galago Pro, but I really wish they'd open up or partner with a reliable distributor in the EU to lower shipping costs, provide localised keyboard layouts, and avoid having to pay VAT at the door.
Edit: ohhhh! You want non-touch but 4k. Now I see! But if it's paying for unwanted touch functionality vs a US keyboard layout (not to mention the vastly inferior design and size) then I know what I'm picking.
