Win 10 Laptop 2/1/ Tablet Help

I have an old faithful Dell XPS 10 years old that has been brilliant and still is with the SSD I installed (Win10) but I also have a Nexus Tablet that I use for reading (RB Digital App) a lot. The Nexus is needing the battery charging every couple of days and I suspect it' son it's way out. My thinking is it will probably be better to replace with a windows device and as I haven't been in the market for anything for about 10 years the choice is bewildering.
What I want it for:
Reading - so lightweight and possibly 12" + screen
Normal internet browsing
Running MS Office
I also need to be able to load some old software on it (Quicken2000 that does run on WIN10) - this bit is a non negotiable as I have accounts on this going back 20 years (sad I know )
Oh and the ability to connect to a 4k monitor.
Budget as low as possible but definitely no more than £1,000

I would go surface pro, with the dock.

Yes choice are almost endless 
Losing the will to live sorting out what spec I'd need!!

Well in good old money saving style I've decided to leave it until they give up the ghost.  Basically I'm not sure either of the devices would double up as a useable reader so it would have to be a tablet and a laptop.  Laptop specs are both coming in over £1,000 although the XPS would be my choice again I can't justify the expense
My last XPS set me back £650 and it's been great.  SSD gave it a new lease of life a couple of years ago. Just need to make sure I keep backing stuff up a bit more!
