I'm like Lcuk, in that I want better and more importantly intelligent integration between my device(s) and my environments.

I would like one device to be a central hub for all my converged information and media

When I am out walking the dog or cycling (or whatever), it will have maps available, play music and rout calls though my bluetooth headphones. When I get to the car it needs to automatically connect to the internal car router and wireless for internet access - maps which should have a learning mode of favorite locations, deciding which one is likely based on the day and time and calendar entries, downloading smart traffic info for the route etc. It would also then re-route music and calls through the in-car system.

When I am at home, and watching TV, I want my tablet and DVR to communicate, and for my DVR to pull information and updates I want such as news, friend updates, etc from my tablet and overlay them onto the screen I am watching. If I am at my desk I want to be able to hook my tablet up to a large screen and full size keyboard and use it like a full on desktop or laptop system.

There is quite a lot there which is doable now with the hardware we have. The software would take a bit of work though, and I think it would take another couple of software generations to get there though.
