I like Hotmail, not because of spam filters or features. I like it because its dammned reliable. HotMail is ever-present on the Internet, and alot of folks take that for granted. In the 4 years that Ive been using Hotmail, Ive never once experienced an outage of service. I really like Hotmail for this reason.
Hotmails always fast, too. Ive never experienced a day when Hotmail moved sluggishly.
People may say Hotmail Sucks! or something of the like, but I will always know that Hotmail is the best because its omnipresent. I enjoy the easy interface and quick pageloads, and especially the reliability.
