I've been putting off (for a long time) one big, complicated user requested feature on my mobile app to do with archiving/managing a local database on the mobile device. It turned out that the things I thought I needed 12 months ago I don't really need at all, so procrastinating about it actually improved the delivered experience.
I do procrastinate, but I think it's a useful trait when you find yourself dealing with a big organisation that tends to throw off useless tasks because somebody feels like if they aren't producing requests, then they aren't being productive (middle management disease).
