Leave it to a Texan to recommend leather vests and holsters!
Well, maybe not vests for me, but I've done jackets with good-sized pockets before, so I could see something like that. And some of the bags are a lot like camera bags.
And in reality, I don't have a problem with "man-bags" (I tend to wear them on my belt in the hip position anyway, so they look a lot less geeky)... I've just gotten out of the habit, since trousers and cargo pants, even shorts, are coming with more and larger pockets these days. By the time I buy a UMPC, my cargo pants pockets might be big enough to hold my current laptop...
