I'm out shopping or eating I'm not so stupid as to take my work with me. For some people, like sales people, taking your work out with you is possible, for many people, like me, it's not really possible to take it away from the desk where I can create in comfort and peace. It's hard to do good creative work standing in the middle of the street, a busy shop, or a busy restaurant - thus no need to take work with me via a mobile device.
Nor do I see a need to be addicted to checking me email every five minutes, it can wait until I get home and want to check it. If it can't wait, then the silly bugger sending it needs to phone me and talk to me.
