I also did, and had written code for/on other mobile devices before, and did write a large number of even very ambitious software for other mobile devices later.
I do not see any past constructive experience as a waste of time.
Did you write anything for Symbian or PalmOS before WP?
Yes, absolutely. (Actually, "this friend of mine" goes back to programmable calculators ;) - my very first versatile palm computing devices.)
