Looks great but....
I don't want to be the outcast here but aftering viewing some information, I would be questioning exactly what your cost would be for this service. First of all, they don't have a Price Listing for all their services and some that I looked at gave me the impression that you would be nickled and dimed after a while.

Take the CRM option - you can get some free features - okay, but then if you exceed your limit for storage space it's $$$, if you want Outlook Plug-ins it's $$$$, if you want to retrieve your data it's more $$$$ and not to mention you are already paying a monthly service fee and all the extra's are based upon a monthly charge also.

I think it would be more benefical to purchase a CRM product that you own and you can get 'Enterprise' additions that allow you access it from remote locations.

This is just my personal view and I was disappointed when I started figuring out all costs that could add up.
