That's about how many times I fell during my first couple of weeks going clipless and with speedplays too. First time was in my living room (right after I has mostly incorrectly installed them on my brandy new shoes). Second time was a mistake on my part - I started in a gear combo that said "no forward movement for you!" and over I went. Third time was a week or so later after I was more experienced - me and a patch of deep gravel had a misunderstanding and over I went again.

Now, some 6 months later, clipping out is so natural I barely think about it. Most times when I clip in after a stop I can get it on the first rotation of the crank, something I just couldn't imagine when I first started. I am in the clipless camp now, not saying that going with platforms is out of the question though. I am seriously contemplating changing my pedals once winter gets here and I need to commute in the rain or on wet roads. Wet feet suck! I have a pair of power grips that I may put on my commuter bike but I will stay with clipless (Speedplays) on my new bike.
