Won't there be more channels on freesat though?
I've read that freeview is now full and there'll be no more new channels coming to it.

It's not a premium rate number; it's in Kent. But that aside, it's hard to know... if all the techy people are the ones who use online resources, like the Toppy forum, then given that there are an awful lot more Toppys sold than there are forum members - and we do encourage them to sign up, for example by restricting beta downloads to members only - I still think it's fair to say that the very techy users are probably still a minority.
