sure its good news that the apps are selling, but its not as rosy as it seems. there aren't millions of apps in the app store, last time it was checked it was around 500k different apps, now its probably around 600 to 750k. A lot less apps are sold in hte iPad, hence the higher ranking. 500 for educational app in the iPod doesn't seem high to me AT ALL. Like I have said before to put a dent in some actual sales you need to rank top 100. With awareness, some marketing it could happen. I was expecting a much better PR.
