The Huffington Post did an article on 20 Things That Became Obsolete in the Last Decade. I'm pretty young (shhh... don't tell anyone) so a lot of these things I absolutely agree with. Although, I will say that in my job I use a fax machine still pretty much daily. I also have a number of catalogs delivered to my home for decorating inspiration.
Also, number 5 on the list? Bookstores. Agree or disagree?
