I've had a Hotmail account for years without any problems. Hotmail generates revenue through advertising. Whether it makes a profit is another matter.
Google also gives out a couple of gigs worth of storage. I'm actually more paranoid of Google reading my mail than I am of Microsoft. Google knows far more about me than Microsoft ever could.
Yahoo mail now has unlimited storage which is quite cool.
As for Facebook, my wife and I set up accounts last night (after being badgered by people to do it) and from first impressions, it's crap. I really don't see what all the fuss is about. Perhaps I'm missing something.
With Facebook, it's scary just how much information they want about you.
