I was reading an article today on ReadWriteWeb: "But even still, refreshes provided by updates may not be enough. Flurry is seeing a trend that, to be honest, was surprising: only 10% of users are updating their applications after download. That means new features pushed out via an update aren't being seen by a large group of the app's users. " http://www.readwriteweb.com/archives/the_state_of_the_smartphone_iphone_is_way_way_ahea.php I believe it. Looking at my iPod Touch right now, I have 25 updates available that I haven't downloaded. There are a few reasons I don't: a) The update is for an application I don't use or rarely use b) The update says it will erase data (high scores / progress) c) The update is for 'bug fixes' and I haven't had any problems There's probably a few more reasons too. Point is, if people aren't downloading updates, what's the point? The best reason I can think of (and I don't fully understand how this works) is that updates boost your application's visibility in search. I assume it causes your app to show up as 'new' in some lists, which drives sales from new customers. I certainly appreciate free updates, but I'd say I upgrade less than 25% of the applications I have, including those I paid for. Any thoughts / anecdotes?
