I invite people to have a look at the street view at the map location you've given. It seems like a perfectly wonderful place! If I were to move back to the UK I would pick a place like that over London any day.

I don't think programming ability is actually related to love of large city centres :-P Certainly it is much easier to hire in large cities, but I'm sure you can lure the ones who prefer small towns out of London if you offer them a competitive salary. Whether Dyson is interested in doing that or not, I have no idea.
