Hi Adam
Well, the thing was that my Android phone, which I didn't connect to the internet much, was useless for the first half hour because it always seemed to be busy downloading updates to thing I didn't use and couldn't delete, like Google Play. So I wanted a technology that was stable (i.e. no more updates) - hence Windows Phone 8.1. Now you know.
Cheers
p.s. Unfortunately, Microsoft seems to be blocking me from downloading the likely looking alternative browsers, Opera Mini and Nokia Xpress - a stern "not available for your device" message, but I'm trying out Surfy and will report back (in case there's any other Windows Phone 8.1 user)
