Apple is set to rollout Top 100 lists for each category in the App Store, according to the developer of the iPhone App Save Benjis (iTunes link). There are separate lists for the Top 100 paid and free applications. You can see a screen shot of the lists in action above. The screen shot is of the Top 100 free apps in the utilities category (iTunes link).
This is a welcomed addition to the App Store. There has been a lot of chatter lately about App Store pricing. While this is great, I’m still waiting for app demos! I think the ability to demo apps are holding back sales. The lack of app demos has been the main reason I’ve only bought one application from the App Store.
