Don't have a problem with GPS - even have one fitted to my aircraft.
However - when operating into an airfield which is notified in the UK AIP as being available for VFR flights only then you should abide by VFR - which means head out, especially when the day in question is just above VMC minima. If people wish to fly head in then they should operate iaw IFR which includes operating into IFR notified airfields.
