LOL if only it was OSX on your mobile phone as insane as that sounds, who in their right mind would still want to use OSX on anything.
More like 2/5, if I give you government (all 50 states and federal too?). You see the price conscious private sector not rolling out OSX powered machines for their rank and file, unlike the "government." Man, that'd be a cool movie. Imagine Hunt for Red October having the sonar being auto-tuned on the G5 and the comms station.Lets think:
Video Designers/Photo Editors etc. - Check.
Governments - Check, US Gov just bought a bunch.
Companies - Check.
Education - Check.
Gamers - Not so much.
4/5 looks pretty good to me.
