There is already a scam alert about this "service" here: http://drupal.org/node/211166
I just thought, I'd share my experience with you guys too, so that you don't fall victim of their false advertisement, and get burned the way I and my friends did.
The features they advertise do look pretty good, but for your own sakes DO NOT FALL FOR IT. This "service" is a DISASTER from beginning to end, it is simply unbelievable that a "service" of this quality and this much contempt and disrespect to the customers is still around.
First of all, you'll be lucky if your uptime is 60%. Yes, half of the time you or your users try to access the site, it is down. Disks fail, servers shut down ... and on, and on and on ... The other half of the time, it is up, but you have to be REALLY patient to get the page loaded, it is so slow, I sometimes think they are just typing the content in by hand as it is loading. I was running a standard BB engine there, nothing fancy.
