I've been using a few android devices (phones and tables) for a couple of years now. Many android apps come with an auto sync feature or alert which fetches information and alerts while app is closed. For instance, RSS apps can be set to fetch new feeds immediately and notify you. News apps like CNN can send a notification when there is breaking news or any type of news depending how you set it up. Apps on the Iphone has this ability too if am not mistaken.
To my big surprise, all apps on the ipad need to be launch before they sync and fetch. Which means you don't get no notification. Nothing can be synced in realtime. Even third party calender apps need to be launch on order to retrieve events from a online calender like Google. Am I missing something? If this is true then I'll need to sell my Ipad as fast as possible as it would be very useless for me.
