Congrats Yen on your going clipless decision, I think it's the best way and I was very hesitant on doing it, glad I did!
Falling seems to be just part of the initiation of going clipless, I think we all have our "horror" stories about our first fall, I know I do!! Oh, and my second and third too....so you see it could be worse! ;-)
You're right about having to think each move ahead of time at first but soon it will all be like second nature. But by and large the best move was going clipless, lots of advantages to it and you've name some of them, one with the bike and hills are easier.
Good luck and most of all have fun!
Life is like a 10 speed bike, we all have gears we never use.
