Nope, not really unrealistic. With new builds springing up and more and more empty shops and other buildings being converted into flats... I think it's going to be a very real situation to think about not too far in the future.
But, whatever the reason for it being asked is, it's still a reasonable question right?
And if I did upgrade to fibre 500, it would be me that would pay the price for it. So I don't really see why I should have to be looking for unrealistic situations to kid myself? £10 extra a month is a lot and nothing to laugh or kid over. 😕
When I make a big purchase or decision I like looking at it from all angles, don't you guys?
