I run a small business and want everyone involved to be capable of "running the office" from the road.

A.* can I receive and send faxes and emails from a 650? If I can't receive faxes can I be notified of faxes arriving in the office?
B. can I PRINT from a 650? wirelessly?
C.* can I edit (OCR?) things I receive on a 650 and send them?
D.* how cross platform successful can I be with a 650?
E.* can I conference call from a 650?
