The notification system in iOS sucks. Especially on the iPhone. That's no secret, but it bears repeating because it's gone unchanged since the first iPhone was introduced in 2007. Hopefully this is the last time it'll warrant complaining about.
If there's one thing at the top of our iOS wish list, it's for a better notification system. Especially now that Android and webOS have figured out a way to make notifications seamless and unobtrusive, Apple's roadblock system has become seriously outmoded.
