Pants
I'm testing a new style of trouser that features special PDA pockets. The ads don't quite call them PDA pockets, but that's their size and their function. So far, it's very pleasant indeed: much more comfortable and also safer, for example, than using your shirt pocket.At one level, this is mere consumerism. But it's also the way clothes evolve. Whenever I buy a jacket, I need to choose details (one vent? two?) intended to make you comfortable on horseback. I rarely ride a horse to the office. Decades hence, will people buy clothes with PDA pockets even though PDAs have become an archaic memory?
