Hotmail. That's a free service, right? People always want to get something for nothing. You get what you pay for. If you get it for free, what kind of support or guarantees can you expect?

Now, if you're paying for a service, that's different. Then, you ahve to be aware of the SLA's and the fine print in the SLA's and the licensing agreements. I know people who own small businesses and they like the fact that they can run their technology free or nearly free. But, they are oblivious to the fact that their services can and will go down and be unavailable when they need it most.
