How will the app store differ when it reaches 300,000 or say an unrealistic 1 biiiillion apps vs. the current 100,000? Will we see a large increase in the average number of apps being used per iPhone/iTouch? I don't think so. For every new app I download and plan to keep, I usually delete one I'm not using. Let's call this the LIGO method of app management or Latest In, Garbage Out. The average usage difference between the apps I use daily (5-10) and the remaining apps (50+) is huge. I'm guessing that's true for most people and won't change no matter how many apps become available.

My obsessive app prioritizing is probably not the norm - I'm sure there are many people who just keep accumulating apps until they reach the 9 screen max. Either way, your organization behavior with apps is most likely very similar to how you manage blog subscriptions, your desktop, people you follow on Twitter, etc. Let's not forget about the problems that start to arise when you have too many apps on your iPhone including: slower performance and freezing, too many app updates, low memory, and decreasing battery life (steady improvements to hardware/software may address some of these issues). On the other end, Apple will have to keep hiring more people to try and keep the app store clean. As long as the quality of apps increases and Apple continues to manage the app store effectively, I'm all for the rapid growth. And the rapid growth will continue as long as we keep seeing success stories from the developers themselves who are increasingly starting to reveal sales figures. I also wonder if Apple should phase out featured apps completely (but keep Top lists) similar to how Twitter hopes to abandon its suggested users list. In the future, I hope to see them make less "App Store breaks 200,000 apps" announcements and more announcements about improvements to the app store. The other major players like Google should also focus on designing a better app marketplace, then maybe people won't care as much about them always being behind in total number of available apps.
