I think it's a power thing because they're manoeuvring for negotiation.
Translation: "I can't be bothered to spell because you're teensy and I have another $1B to spend today on companies 100x bigger than yours. Make with the paperwork chop chop."
Then, confirmation: "Give me your mobile so I can call you any time I feel like to make you jump, because you're the bitch now."
Yeah. My reply to that message would have been "I only give my mobile phone number to friends. Please use my office line between the hours of 9 AM and 5 PM EST."
But honestly, a lot of people seem to like doing business deals while walking around with their cell phones, so perhaps this is not actually a power play.
It's funny how they refer to Schmidt, Page and Breslin as "the board" since it's obviously just 3 people :) In any large company you only use the "board" wording for a committee that's at least 15-20 people.
