I like that it lets me check my emails from any computer, so i can keep up with work while traveling or away at family functions. It's not as intuitive to use compared to gMail which was one of its competitors. If you want something simple but reliable then this may be what your looking for. Its great if you need access to all of your email accounts in order to stay organized. Being able to log into multiple different ones allows us to have more control over our inboxes than we would otherwise without having separate systems.
