Samsung Galaxy Tablet

[Bucknaked]

I purchased a tablet for my son for his birthday and I've got a question for those who use these types of devices. I noticed that apps continue to run in the background when you hit the little house icon. How can I make apps shut down automatically so when you go back to the main screen, the app has closed. I know I can hit the other icon next to it and close them one by one, but I'd like it to work the same as my iPad when you hit the home button.

I know multi tasking is a great thing. But when you have a child who might play 4or 5 games in a short period of time, having them all running in the background I assume will impact performance and shorten battery life.

I quite like the Samsung tablet. It's a cool little device.

Thanks
