Yes it is stealing and unethical to boot. Proper behavior would be to return it to the store then the person who forgot the item can reclaim it and be so very happy that their hard earned money is not lost.
Stealing is the unauthorized taking of something that belongs to someone else without their permission. It is considered a criminal offense in most jurisdictions and can result in legal consequences.
You could call the police.

I'd think not.
Stealing is illegal because you are taking something that is someone elses, they worked hard for it and someone is just taking it when they didnt work for it. if you have permission to have it then it is not stealing however.
Window shopping may never result in any actual purchase - although it is also possible to window shop, see something you like, and buy it, in which case you did not waste your time (assuming that your purchase is well chosen, and not some junk that you don't really need).

Stealing. If someone has something that you believe is rightfully yours, you should use proper legal channels to retrieve it.
'Sharing' is when something is given willingly by the rightful owner. 'Stealing' is when the item is taken without permission.
