I've used them for six years on a paid (enhanced) account and they've been very reliable for me. I've never noticed any downtimes and I appreciate how fast their web portal is when I need to mess with my configuration. There's also been zero issues with CalDav.
I'm sure other providers give similar access, but they also make it very easy to create alternative email addresses for the domain I own. Once I started using them, I started setting up a different email address for every company I did business with online and that's cut down the amount of spam I receive dramatically. Basically, when I see a compromised email address, I disable it and that seems to do the trick.
In any case, they've provided me rock solid service and that's worth the $40/year that I pay.
