One of the best features of iPhone 4 is that it records video in 720p. As with the iPhone 3GS, a lot of people have been asking whether that functionality will kill the Flip. I think the answer is still no, but it will eventually turn into a yes.

The problem is that the iPhone still isn’t prevalent enough. There are plenty of people in the world who are scared of smartphones – unsure that the additional cost of a data plan is actually worth it. For those people, the Flip is still a great option. It’s cheap, easy to use, and records great video.

As smartphones become more and more prevalent, though, its inevitable that the Flip will die off. As I’ve said plenty of times about the Kindle, I still believe purpose-built devices are a thing of the past. The Flip is no exception. The more advanced our daily handhelds become, the less we’ll need things like a Flip to fill the gap.
