As I see it, free live radar feed sites such as this one are now giving such good area coverage, with plots no more than 15 seconds behind real time that the 'out my window dot spotters' and enthusiasts who only have a general interest in what's going on in the sky around their homes, (and I'll bet the majority of users are), will have no need to spend hundreds of pounds in purchasing a virtual radar box and will surely consider what advantages buying one would bring for the outlay involved.
Not only that, but for those who are interested in what may be heading their way or even what's going on further afield in the UK and Europe, this site together with several others, give such good coverage that before long there will be very few current box owners who will pay the not inconsiderable cost of network subscription. Unless you are really interested in flights in far off places, there appears to be little point in doing so.
I'd be interested to read others thoughts are.
