I have one, well three now. I use the video facility quite alot aswell.
Just got the Mrs one, £17.50 a month for the first 6 months, for 750 mins of anytime/any network calls. Even then it only goes up to £35 p/m
I got my first one last May, when they had only been out a month or two, they were cr*p then, I must admit.
Now though, I get very little, if any problems. But then again what do you expect for £35 p/m, for 750 anytime/network calls a month when everyone else is double that. I certainly can live with it, especially now they are alot better.........
