The information you provided at the very beginning of the post is really very surprising. When the i phone was launched in the market, it came to our attention due to its attractive features like- storage capacity andgames apps. But if the attractiveness starts going down gradually after buying it, then it is really a shocking matter. In your post, the graph has played a very important part to understand the whole thing.

Interesting stats, and I'm not surprised. I find that many apps outwear their usefulness within hours. The real challenge is creating something that not only appears novel at first glance but can be remembered as need-fulfilling after the fact. This is not only the case for paid applications but free ones as well; for example, the zippo lighter app is cool for a bit, then the cheap fun of quickly wears off. Ditto most of the movies apps I've found, since it's easier to simply look up showtimes in google. I'd say the only apps in my iPhone with any longevity have been Yelp (always great to know what I'm getting my stomach into) and Taxi Magic, which can book/track cabs in most major metro areas. I should point out that both of these are of particular relevance to me since I travel a lot on business, but I could see even using these two in my home town. I think the only way to transcend the curve is to fulfill a real need.
