I used it once with a Mac to new iPod touch test call. It has its uses, but with the current restrictions to Wi-Fi, iOS devices, and Macs actually getting to use it is few and far between. Right now, it suffers the same problems as iChat (which it is redundant to), works great but their inability to work with others limits practicality.
Like I said before, the best way to do this would be to create a wholly owned subsidiary for business sales outside the reach of jobs and Ive. This company would be able to create types of computers that the enterprise markets want, but does not fit within the typical Apple schemes.
