Which 2 in 1 Laptop

Cocksure

Hi,
Hoping someone can recommend which out of these 5 2 in 1s would suit me best
It's being brought primely for REW (Room EQ Wizard), I'm sure I will use it for other things, but that is its main purpose. Gaming will never happen on it and I don't need a huge amount of storage, just need it to crutch the numbers well. I will be using it outside in my van quite often so a bright display would be nice, but I don't need accurate colours or wide viewing angles, etc.

Got it down to these 5 going from cheapest to most, I would prefer the cheapest, but if you think the more expensive ones are a better option then I'll push to them. Anyhow this is my current shortlist unless anyone has any other recommendations
