Don't get rid of it!
I still have my original hotmail account from 8 years ago...back before they were picked up by Microsoft. I use this account as my Utility Account. Whenever I have to register on a new site, or something like that, this is the address they get.
If they're going to send me a bunch of junk e-mails, just for logging into their site, they'll all get deleted along with the rest of the 40 or 50 or so I get there each day. Saves having to filter through it for one that I'm looking for. Heck, I'm pretty sure no one I know even knows that address anymore.
