While we can't honestly imagine an iDevice user going about their life without connecting to the iTunes App Store at least once in a blue moon -- if not on a semi-permanent basis -- the statistically-significant NPD Group decided to look into the matter regardless. Sure enough, the org reports that a full three-quarters of iPhone and iPod touch users in the US do indeed download apps and entertainment content from the internet. In case you're wondering, that figure beats the pants off those connecting from their video game consoles (19 percent) or Blu-ray players (17 percent), but both of those are obviously biased towards physical, disc-based media. Before you dismiss these findings as obvious, however, let's read between the lines -- if 75 percent of Apple's touchscreen devices are pulling content from the web, that means the other one-quarter have gone without. If not apps, what the heck are those devices being used for?
