Would you still be happy if you'd spent millions getting those 440k users?
For $41m investment, you could pay 410,000 people $100 to become a user.
Given the amount of funding it required to get that many users, and the lack of a clear business model, I think that their active user count is about as relative as where they leased their copier from.
I wonder how many of those 440,000 "Active" users were a result of their partnership with Verizon to install Color on a bunch of their phones.
Also, does "active" mean # of installs in this case?
