Yes... the question of whether phones will become cameras isn't answered yet.

I think, myself, that cameras will become phones. But the problem is, which is the essential item?

Today, no doubt about it: it's the phone. I'll leave other toys behind, even when going sailing (especially when going sailing!) - but I'll risk taking my phone, just in case.

My camera may make me a little money, but my phone will possibly save my life. Now: will I risk running down the battery on my life-saver, by listening to too many sound tracks?

It remains to be seen!
