Even though I'm taking pictures it still never feels like I'm taking enough. Most of the time it's merely observational, walking around and seeing something that catches my eye. The problem isn't that I don't like doing it, but that compared to the creative kick you get from realizing an original concept.
A side-effect of not taking pictures for a while is that I start thinking more about gear than actual ideas. Of course it's a useless path to constantly look for the next camera, but even I admit that some cameras just have a certain allure about them. Fuji's X-system has that certain something.
As for what is keeping me with Canon... nothing in particular, apart from the current lenses I have. (To be honest, based on current sensor technology I would advise someone starting out today to go either Fuji or Nikon.) But I would not be opposed to going with a dual system either, as I would keep the Fuji for events where a lower profile is needed.
