If you want the latest and greatest USM, IS etc, go out and get it, but it really won't make you a better photographer.
Boz clearly stated that he is "a technical head more than an artist", and I can understand his reasoning. It's his money, and he's free to spend it as he sees fit.
And I bet that whatever he does, he won't post here "Pentax s***s, Canon rules, you are all a bunch of morons" messages, like some distinguished pdml subscribers are doing.
