Ok, so this topic has been done ad nauseam but I want some help. My situation I suppose is a little unique. I'll list what I'd like to do and what I currently have.

First up. I travel for work. Quite a bit. I'm away from home seven weeks out of eight but I'm usually home for weekends. 

What I want to do, I have several GoPros, a phone that records in 4K, and a Sony RX100 that records in 4K also. I'd like to be able to edit small clips into movies and chuck them on YouTube and share them. I record my friends playing golf and riding mountainbikes so the finished product is never more than a few minutes long, and I'll upload so we can watch. And laugh. 

However, I don't have a laptop capable of editing 4K content, so I'm trying to decide to just simply replace my existing laptop (which is actually a Samsung hybrid tablet that I never use as a tablet, Windows), my actual tablet or my phone. 

I generally take the following away with me.

Work laptop. Locked down, cannot be used for anything else.

Work iPhone. Locked down, cannot be used for anything else.

Nexus 7 2013 LTE. I love this dearly, fits in my pocket, walk to dinner, peruse news and I have the odd app I don't like having on my phone (Instagram, Facebook, which is just a Chrome bookmark) etc. But the touch screen is becoming glitchy and the battery is giving up. I also like having it in the glovebox as I'm able to check some non locked down work stuff as well. 

LG G4, works well. I use it for music and photos etc. Has a new battery

Samsung ATIV something hybrid laptop, absolutely basic, but boots fast and I just use Chrome really. 

Various GoPros and my wee Sony Camera.

I rarely watch video on anything, I have Netflix and YouTube obviously, but spend little time on it when I'm away.

Should I get a grunty laptop (Dell XPS 13/15 something else?) to replace the existing hybrid, let my tablet die, or is there a do it all device?

I like the lightweight aspect of Ultrabooks and battery life would be useful, but not essential if a gaming laptop (which I know nothing about other than they have large screens and dedicated graphics cards) would do the job. Is there a grunty tablet that would do all this? Fewer chargers would be great, I already bring a 5 way Anker charger with me, laptop chargers tend to be a PIA. Or are the newer phones capable of this sort of thing? Bearing in mind getting stuff off the camera needs a physical connection for video.

What are your thoughts callers?

Edit. I'm leaning towards a six inch phone (Note or Pixel 2) and a grunty laptop or tablet? No Apple products at this stage.
