Not a pipe dream
We have approximately 50 employees at my company and by the end of this year all of them will have docking stations and laptops with 24" dual monitor setups. Currently all but 4 or 5 are already set up this way. Approximately 1/3 of those employees are engineers with AutoCad installed on their laptop and have no problem running it. We have desk phones but are using a VOIP solution that allows re-routing to a cell phone. Our sales and support staff spend majority of their time working from home or on the road. The company makes and installs automated conveyor / picking / palletizing solutions in the beverage industry and all our installations have 15-30 cameras with HD resolution to monitor critical areas which the support staff can remotely access to aid in solving problems as well as remotely access the servers at the various installations. So I wouldn't call this a crack pipe dream. This is a medium size manufacturing company which recognizes the need to be mobile. The prior company I worked for as a consultant was the Corporate Data Center for Time Warner Cable with over 400 programmers, analysts and managers on laptops.
