Communication, organiser, maps, instrument tuner, note taking, photo taking, web browsing, and so on. Everything that my current phone does, really. My current phone (HTC Hero) has changed the way I do things - I'm so much more organised now, and have got used to having everything at my fingertips.

And my current phone will be my development phone - I want to start building apps for Android, and I don't particularly want to put things on a phone that I use constantly.

I'm a massive gadget nerd and a huge fan of Google, you see.
