My house is full of gadgets that now cost a quarter of what I paid, as a "must have" early buyer.
In the case of TomTom, I have no regrets, if I'd paid £1,200, it would have been value for money: No arguments with Mrs.B. over map reading; No wasting time having to pull in and study maps. Just once, it sent me up an impassible road in the motorhome in Mid-Wales, but I notice that that has been corrected in updates.
