Since my first book came out, over its whole life, half my sales have been paperbacks through Australian boookshops, a quarter paperbacks through online retailers (via Createspace), and the remainder Kindle editions. I've only brought my titles to Kindle a few months back (late March for FoO and late May for OH).
If I look at my sales based on just the last month or two, now two thirds are Amazon Kindle editions, while the remainder are paperbacks split all over the place.
My second book get's a paperback release locally in Australia in a few months, so that'll throw the figures out in favour of that avenue again.
I love the Kindle sales (who wouldn't), but the bookshop sales are also lots of fun - particularly at book signings or when you see your title on a shelf with a recommended tag underneath it.
I'm not on Smashwords yet.
