Email clients.

Just Hotmail.

I use Gmail and email.unc.edu, for personal activities and school activities respectively. I prefer Gmail over everything else I've ever used because I can file everything neatly away and nothing ever gets lost once I put it someplace. Also, I find it's much easier to navigate than anything else I've used.

My school email is absolutely awful. It only displays fifteen emails at a time, and the folder option takes you through several different pages before you can even access any of your personal folders. I hate it.

EDIT: Also, when I want to compose a mail or reply to a mail, it pops up the composition page in a new window which is SO annoying.
