This picture, which I secretly snapped on my phone en route to work this morning, sums up a new dilemma to me. And it's nothing to do with the crap antennae on the iPhone 4. The iPhone, as we all know, is good for playing with, and will keep a pub table of friends entertained for several minutes as you pass the handset round to let everyone have a go at Paper Toss. The Blackberry, however, just somehow feels more grown up and proper when you pull it out in a work situation. I have heard rumours of some possibly too-well-off people owning one of each, one being for work and the other for play. Is the previously-predicted age of the duo-phone upon us, one wonders?
