Google Drive has a Trashcan and everything stays unless you empty the trash can
Amazon Cloud drive has a Deleted items area and everything stays unless you permanently delete it
Dropbox has a previous versions option and it lets you undelete anything from the past 30 days with a free account.
Not having this ability in SkyDrive seems very disappointing. And considering how easy it is to accidentally delete a file from any synced computer and losing it in the cloud and everywhere else really stinks. Looks like I am going to be mainly using one of the other services listed above.
