The Way it Goes

I heard an item on the radio today (BBC) about how people are tending to go into bookshops, browse, ask advice, chat to knowledgeable staff - and then go home and buy the book they've been researching online. Yes? No?

I am increasingly reading fiction on my Kindle, if only because of lack of shelf space and because the weight on the device is so much less than the pages. But being an author, am I ultimately spiting myself and my writerly colleagues?
