I think "secure" and "cloud" are pretty misleading. In terms of security (if it's about my personal mail/calendar) my bigger concern would be that my data is lost, e.g. not backed up properly, deceptible to hardware failures. As for "cloud" - I can't see much on the page that would have remotely the same properties as a "cloud" solution. Maybe that's why they put it in quotation marks? Still, very misleading imho.
There are steps taken to address security and stability concerns. See my other commends on this item. Also you may need to look beyond just the front page - can't put everything we want to do and plan to do on the front page at once. :)
