Used Kindles for years my latest one is a paperwhite with 3g connectivity. But it's on the blink, very slow and keeps freezing. I've tried switching in and off and updating it. I think im going to have to buy a new one. There's several different models and I cant see a difference and I don't think they do the 3g version anymore does anyone know if there's a massive difference ir should I get the cheapest. Just to add I use it every day.
