Android Market keeps looking better and better when compared heads-on with the iPhone's App Store. Android Market will accept everything and deny nothing while Apple's policy is confusing and kept in the dark. So when Andy Rubin announced that there will be a free trial for paid applications, many developers are beginning to become very, very interested in the Android platform.
Having a free trial for applications is good for both users and developers because users aren't locked into buying an application they might not use and developers are able to give users a taste of their work. Android Market will certainly receive a lot of attention from iPhone developers if they keep offering everything that developers want.
Which will obviously mean more apps for Android. Sweet.
