"He merely said that whether it's a tablet or a laptop or a desktop, it's still a personal computer. Fair point."
If the best reaction you can muster from a question such as the one posed to Ballmer is "fair point", then the speaker hasn't said anything of any significance or depth.
Contrast that with Steve Jobs' answers, and the difference couldn't be more clear. Either Jobs is far more skilled at veiling his true intentions, or he's a lot more introspective. Personally, I enjoyed listening to Steve Jobs' answers a lot more than I did Steve Balmer's. Ballmer just sounds a lot more like your typical corporate "talking head".
He didn't say anything worthwhile either, just weasel words.
