Lets start a thread to gather thoughts on what the perfect phone would
be. I'd came across the OHA magic phone video (http://www.youtube.com/
watch?v=jWtFeIw8MVM) which got my mind thinking about gathering more
serious input from others.

I will throw in one just to start with: a perfect phone would help two
parties meeting up to find each other simply by showing Left/Right/
Forward/Back arrows. This would save the ~4 calls I need to place,
getting irratated each time to ask my partner "where exactly are you?"
when we both arrange to meet out somwhere new (her responses are
somewhat vague). It would also be nice if it could show you what mode
of transportation the other person was on (fairly easy to work out I
believe with a cheap accelerometer) - this would mean you would know
when the other person had actuall left the house etc. so you could
factor that in so as not to arrive too early.

I've got plenty more...But lets see what others have in mind.
