Looking for a small laptop

Solution
The Pentiums are, as far as I know, a bit higher in the spectrum than the Celeron in the original. The one from currys with the a6 probably has a better integrated gpu. But wouldn't dare say for that for certain.
Max is really £300

I live near Manchester, UK
My nearest computer stores are PC World and Scan Computers (Scan is very very good)

I'm looking for one that I can use in a coffee shop and also on the train but also portable enough to fit in my backpack which has an area to slip a laptop in.
 
Seems reasonable for 300GBP. That's not my neck of the woods though so I am not the best source. It'll do basic browsering and office work. Not going to do much gaming (if any at all) Win7 is running about 150USD over here. I know win10 isn't terribly appealing especially if you mind your privacy, but it is a decent OS. So maybe you can save some cash. If you have a student ID you can get the student version of most OSes on the cheap from a local university, at least you can in the US.
 
What about these:
