I find this to be a little bit disconcerting almost, that it is so easy to take the pictures. Every time I release the shutter I wonder what I missed, and whether I will ever learn to notice it. As it feels today, I much rather use the Pentax, but I know that in low light situations I'll be wanting the Canon again. It's a compromise to me.
You'll find the restraint and become comfortable with it, I believe. It may take some time (and film!) to adjust, but it's not like the camera is stuck in 7 FPS mode all the time.
