This fixation with ever smaller, ever lighter has always puzzled me.

Already these devices are so Lilliputian that they can only be comfortably used with keyboard programs like Swype to correct the inevitable mis-typings. Would your ultimate phone be some fingernail-sized item that you needed a magnifying glass and a needle for input?

I don't own a smartphone, or any cell phone for that matter, so my opinion is probably worthless. But SWMBO has an iPhone, and it seems to me that it would be a worthwhile tradeoff to double the thickness in order to, say, quadruple the battery life. It would still fit into any pocket, and be easier to hold onto.

But what do I know?
