I think if you have the means, you should always get a custom domain for your email address. Your email address is the key to your online identity. You should own it, and not lease it from someone else. And it is not like you have to manage your own email servers. You can use services like fastmail or any number of email providers to receive email on your own domain. You also have the ability to change your implementation without changing your address. You can decide to host it yourself, or go to another provider without having to tell all your contacts that you are changing your email. It becomes trivial to actually give out email addresses that are customized for the service. Instead of me+service@hotmail.com you can give out service@mydomain.com. In my opinion, the money you spend for your own domain for email, is well worth it.
