Why would you dump the desk phone
That phone has a very low cost, where as a smart phone has a seriously high cost.
And personally if they did that to me, the phone would be turned on at 8:30 and turned off at 5:00. Can't reach me after that.
As for desktops disappearing, Funny, I just upgraded my desktop to a new I7 with 3 monitors cause VS2010 is pretty demanding and I like to keep the panels on the second monitor, and my reference material on the third (and code on the first, obviously).
