What is a "business" call? I didn't see a definition. "Just make and receive business calls. As easily as email." Umm.... Most people I know are horrible at email. If I email 4 people and ask a group question, 90% of the time one of them replies only to me with info for the group. Or the reverse, sends a reply intended for me to the whole group, sometimes with embarrassing results. "easily as email" is not a good bar to set.
