I've always used Hotmail, it was the 2nd email service i used, after using Outlook for a few months, i instantly took a liking to it. It's simple, there aren't loads of different windows to confuse you, theres no unneccesary buttons. It's great.

Hotmail allows you to send massive attachments, up to 10GB i believe. It also lets you have unlimited email storage, so don't worry about getting tonnes of emails and having to delete some of them.

The MSN application also links with you hotmail account, so when you sign into MSN, you will receive notifications when you receive an email, or if you have received an email whilst you were offline. Your Hotmail account can also link up to Facebook and Twitter to receive updates about your MSN contacts on both sites. Hotmail also allows you to block certain email addresses from contacting you again.

All in all, its a great service, quick, easy, and has lots of useful features. All my friends use it and i highly recommend it to anyone looking for a good email service.
