[Elecraft] Lightweight Windows Laptop/Tablet for Portable work

[Chas H]

I'm looking for suggestions for a lightweight laptop or 2-in-1 tablet type
of machine to take while hiking/backpacking portable.  I also want to be
able to recharge it with my solar panel/charger/12V Lithium or SLA battery.

I'd love to get the Microsoft Surface Pro 4 but don't want to spend north
of $1,000!

What are others using for a portable Windows that will run products like
HDSDR, HRD. PSK, etc.?

I'd like it to be under 3 pounds if possible.

Thanks,
