Home folder has two Desktops within it - can one be deleted?
The ~/Desktop folder is the one you should keep since it contains your actual desktop. It should be the one with Apple's Desktop folder icon on it.

The ~/Desktop (original) (I presume the original is in brackets) is from Migration Assistant (and/or Time Machine) unless you manually created it yourself. You can take out files that you need and place them elsewhere, then delete the folder.
