According to Apple, Multitasking or running apps in the background causes security problems and it negatively impacts battery life so they introduced Push Notification System. A System which enable apps to notify users even when they are not running. For example, A chat application can now display the latest response from a conversation even when its not running. Here’s our top pick for the apps that can “Push” notifications:

Lots of new features, tons of themes, points and battles, an all new catalog of more than 150 free tracks and three awesome ways to play with your friends.

I would really like to see apps like Skype, Facebook, Tweetie(or any other twitter client) and any RSS Reader to get Push Notification System. Imagine the possibilities when Skype will be able to notify you of incoming call when it is not running? Free iPhone-iPhone calling over the WiFi anyone?
