I just picked up some double-sided SPD pedals on eBay for $20 and started riding.
I didn't like not being able to use regular shoes, so I put my platforms and clips back on this spring. I want to be able to just jump on and ride without having to go inside and change shoes. Also sometimes my daughter wants to ride to someones house after dark, so I like to be able to drop the seat on the commuter a bit and let her ride the bike with full lights.

I may see if I can get some of those clip-in platform adaptors. I really want to be able to use regular shoes sometimes, and I am not really all that in love with SPDs, but they are kind of nice.
