With the increasing proliferation of freemium apps, digging for bargains is now a little harder, as you now need to dig into the app descriptin/reviews a little to see if it's a freemium app or not (I admit, I'm a cheapskate). It'd be nice if Apple labelled applications that used in-app purchases accordingly, so you could filter on those. As it stands, the app developer usually does a decent job of putting warnings in the description, but not always. Also, I'd be mad if I had paid for an app that moved to a freemium model (e.g. F.A.S.T.). There should be a way to support these users instead of asking for their money twice. That said, the in-app purchase model solves the trial problem rather neatly (at least for a subset of applications). I've never written an iPhone application, but it seems like having 1 less application to manage (even if it's a trial version built from the same codebase) is a great benefit.
