"Apps" vs. Mobile Websites

I was sitting with my Lumia 900, wondering how the local baseball team was doing, so I opened the preinstalled ESPN app. I navigated to the game and got a great live Gamecast, which turned out to just be the mobile version of the web gamecast.

The same thing happens with YouTube and a lot of other portals. I don't understand the fuss about a YouTube app. I clock on a YouTube video and it just plays. Sorry.

With more and more mobile web content, will app count get less relevant?
