That's true, but many people have a home server anyway, so this is a very nice addition.
As an aside, after this article I wanted to give Fastmail a shot, but I had already signed up a while ago and then never logged back in. I asked support if they could give me another trial so I could actually try it out, but they said I had to pay. Not great customer support there, especially since I had sent or received zero emails and creating another account for a trial is trivial...
Absolutely. I'm not bothered with allowing an externally facing system inside my home wifi network, and I'm not interested in ensuring I keep my systems patched and up to date. Id also not like to leave a box running 24/7 when I can leech a teeny amount of power from a data entire only when it's needed!
