Where is the trash bin on the IPad?? - Apple iPad 32 GB WiFi Tablet PC

Hi,
As mariolands said, there is no trash bin because Apple wants to make the device as simple as possible for users to use. Actually, if you think about it, a trash/recycle bin is not even necessary as the user does not need to worry about things like that.
If you were wondering how to remove apps, then you have to hold any app icon on the home screen for several seconds until they start wiggling. As they begin to wiggle, you should see a cross in the top corner of each app. To delete an app, just tap on the "x" and it should be deleted.
As for the mail, once you're in the mail app, just swipe right on the message you want to delete and an option to delete will appear on the right. Alternatively, you can tap Edit at the top right and select the message(s) you want to delete.
Hope this helps, -virjog

There is no trash bin on the Ipad. It's part of the simplifying the user experience. Here's an article about that: http://patdryburgh.com/blog/delete-recycle-bins-and-backups-on-the-ipad/

There's no trash bin on iPad. If you deleted some photos on your device, you can check the "Recently deleted" folder. The pics you deleted are stored there for 30 days. If you have always backed up your iPad, you can also try to recover lost files from iTunes or iCloud backup. Here's a guide to show you what to do.
