Good all-purpose 4k touchscreen laptop (full keyboard)

I have little space in a place where I live, so I don't have any desktop. I have an HP EliteBook 8540p, which I used for (and in this order of priority)

- working (coding, loads of typing)
- surfing
- watching movies
- bit of photo editing
- playing games sometimes (including 3d shooters)

I liked a lot of things about that: screen is nice to my taste, awesome keyboard for typing (I like very flat keys), processor (i5) and RAM were good 5 years ago when I got it, and still do the basic job. Of course, the laptop started getting older, and I want a replacement now. I very much like how Retina screens look on Macs, but I specifically want Windows laptop, which I would use for the tasks listed above. My ideal setting is:

- 14-15'', 2560x1440 or higher resolution, touchscreen
- at least 128GB of SSD
- 16GB RAM
- full keyboard (at least PgUp, PgDown, Home and End should be separate buttons, I used to type like that)
- good graphic card (e.g. NVidea G960)
- not much more than 2kg/5lbs

I do not really want to pay more than 1.5k, but I am ready to if it's worth it. The problem is that apparently it is very hard to find anything that meets these criteria, even if you are ok with paying for that. Some of the options that I found

1. ASUS ZenBook UX501UW: nominally meets all requirements. Unfortunately it misses the End button (there's switch on button there, seriously, ASUS?), and reviews of the screen are not great. Also, keyboard is not great to type on.
2. Lenovo Y700: I can configure it myself on their website to meet all the requirements. Meets all the criteria. Have no chance to test it with my hands, can only order it. Reviews do not seem to be great.
3. Lenovo Yoga X1: meets almost all criteria, instead of full keyboard has separate buttons. I would still prefer the former, and 15'' rather than Yoga's 14''. Also, only comes with Intel graphic card. Finally, that configuration would be 2k+, and I have a feeling that I'd be paying for something that I don't need - this extra 2-in-1 mobility and flexibility I don't care about.
4. Toshiba Satellite P50t: nominally meets all requirements, but a friend of mine bought non-touch version of it, and it looks bad. Overall, I would not feel comfortable with buying Toshiba laptop, this one in particular.
5. Dell Inspiron: looks good, meets all criteria. Reviews are not that great, though, and given that its price is even lower than I expected (which is of course great by itself!) hints upon that there may be something dodgy going on there.

Unfortunately I could only see ASUS of all of them with my own eyes, and try it with my own hands. That's why I am worried with reviews about others - like #2 and #5. Also, I really liked HP (besides its fan), and apparently soon there will be some good news on the Envy side. The only concern is Intel Iris graphic card, whereas I was hoping for something stronger.

What is your suggestion? Maybe I missed something in my searches? I would appreciate any help on this topic.
