One global desktop for lawyers ?

Bruce MacEwen writes in his blog about the unlikely chances of one global desktop for fee earners:

When it comes to new applications, the problems he identified are:

"None of these applications:
(a) communicate with each other [certainly not out of the box];
(b) look or feel like each other; nor are they
(c) are intuitive enough to learn that a lawyer, who won't sacrifice a billable hour for a training session, actually has a chance of figuring them out."

So I guess if Knowledge Management then comes in with even one more application, we gotta be really good to get people to use it.
