For photography, yes. It was a great next step in the learning curve, and I absolutely love it.
What matters is what gets the job done and captures the image in your mind's eye, right @bkotsko ? I love my Canon DSLR and Fuji X100T but it was time to figure out the Leica experience. Highly subjective/personal decision.
Put a Leica in the hands of a monkey and you'll still get crappy pics, after all.
I've never been much in to street photography, but it wasn't ever my focus. I've been having a lot of fun with the X100T. Very stealthy, very fast, very good. Thanks for the suggestion.
