35 will broaden your scope -- free you up to shoot more (waste more) and make you a faster shooter.

If nothing else, you can re-sell it for nearly what you paid for it in two years if you change your mind, so the whole experiment will only cost you a coupla hundred. If you have the money, go for it.

If you want a cheaper way to try out the concept, buy a Leica CL and a 40mm summicron lens to go with it -- whole thing will cost you $1,000 and you can get it all back if you change your mind.
