I have WAY too many email addresses. I have three that I use daily- one is for online purchases, one is for networking sites (i.e. Livejournal, facebook, and Myspace notifications), and one is "business", for applying for jobs or taking care of wedding planning etc., a school address, an old one that I use when I sign up for websites and don't want spam in my regular mail.

I think my system works well :P Cluttered, maybe. And annoying. Thankfully I can access my three main ones on my phone. I have a Palm Centro from Sprint and I LOVE it. I do want an iPhone, though.

I am sorry to hear about eBay. I feel the same, that they will lose a lot of their customer base. Thankfully I usually only pay with Paypal anyways, but I think it'll be harder to find hard-to-find items on there now.
