Because Naked Web Cam sites will have your real email and when they find out who you are, and your wife answers the phone, it won't be a good day! lol...just kidding.
Everyone has different email addresses for different things. You don't want clients or customers or even collegues knowing your [email protected] email address, and you don't want others knowing your work email...so yeah, I can see not wanting everyone having one email address or ID for you.
Can you have one device tied to more than one BBID?
I don't think this is possible, i am in the opposite conundrum, 2 playbooks same BBID can't video chat between the two Have to wipe one of the devices. I am kind of surprised that they don't provide for an alias or something that one could use for VC separate from the email address. You would think there would be many scenarios where you might want the playbook device tied to a master user (small biz and family situations) where the device is set-up by one person with the charges tied to that one user or individuals credit card but the device is to be deployed to different individuals.
