The future
Well, in the absolute long term, the mobile networks are fighting the same kind of loosing battle that ISP's fought in the 90's. Sure they will make a whole wad of cash in the meanwhile though, for as long as they can :-)
But in the end, all we need from them is their dumb data pipes - be them 3G, or 4G or whatever else will be around by then. As far as I can connect my Android phone, tablet/pad thing, laptop or whatever else shrunken down device to the Internet through their infrastructure - I don't care about their 'enhanced' services and whatever else they offer. As small devices (such as phones and tablets) will eventually standardise, so that I can efficiently use on the go my email, IM, voip and other open standards way of keeping in touch - I don't need their keeping me tied to various proprietary services on proprietary devices. A simple, reliable mobile Internet connection will solve all my communication needs. You can already do that with a laptop and 3G dongle today - you can send and receive emails, you can make VoIP calls (I've been doing it for over a year), you can do instant messaging. It's just cumbersome, and not as reliable as it should be. But as things improve, it will be even easier to get it all done. So in the end - it is the dumb data pipe that will triumph over 'enhanced add-ons'.
I know, it's not what the operators want to hear - but it will get there. Nobody pays nowadays per email sent, or for specific services to regular ISP's. All you want is a reliable connection with sufficient monthly bandwidth. The rest you can take care of yourself.
Long live the future.
