£150 is indeed more of a sting for something that as you say many won't need / notice.
In Euros it's only adding 4% (to the 16GB / 1TB configuration) though and I'd say that's rather negligible, plus I'm sure getting that upgrade will help with resale value so should be a smart idea down the line.
Back to the original question though -
are there any downsides in choosing i7 over i5 I'm not aware of?
Nope, as cost is not an issue there’s no negative to an i7. When idling it wont use any more battery. Only if maxing out all cores would that be an issue, but then it’s doing the job it is supposed to do.
