I feel I've missed the point somewhere in this 'invention' of Google's. For 90% of our employees they can sit down at any domain joined computer, laptop or thin client login and get their email, network shares and everything they need to work.Every laptop has remote access capability as well. And we've had most of this for 15+ years
It's only those who have specialised software needs that can't do this.
What does this google thing do that's new?
