Being able to link your bank account is a big deal; everyone wins if Bitcoin becomes more "a currency you buy to buy stuff" vs. just something your speculatively hoard -- including hoarders, ironically.
Bitcoin gives you flexibility that PayPal doesn't. You can't opt-out of protections that PayPal gives you in order to streamline your process; you either use PayPal or you don't. Bitcoin allows you to potentially chose any number of companies to provide services to you, or just roll your own solution.
