Sandy has an old Dell computer from 2002. Is it worth keeping? Leo says if it's been in storage for 15 years, it's really not going to do her much good. It could be worth about $25 if she wanted to try and sell it, but it will be a hard one to get rid of because nobody can really use them. The same goes for floppy disk laptops. She won't be able to upgrade it to today's standards, either.
