After having the iPhone 4 for a couple days it has made the pain points of the previous os abundantly clear. The two big ones: lack of unified inbox in mail and app folders. The addition of these 2 features (along with the massive speed bump from my 3G) make the phone a complete joy. But the lack of these features on the iPad make me want to groan each time I receive mail and even think about checking it or when I go in search of an app.

All this will be resolved in the next os update for the iPad, but it will be a long wait.
