The question is a good one. If they can it will saves millions of dollars for businesses as they will not need to equip their mobile workers.
A second question is what will a mobile device be; a netbook, an iPhone or like device, or a regular cell phone?
Can you use current applications or do they have be rewritten to be used on mobile devices?
Is it possible to have a single device or does practicality make it necessary that we have at least a phone and a display/input device?
We are looking at these questions and want to hear what your thoughts and experiences are with business and mobile workers.
