The difference between onstage Bono pre-Zoo TV and onstage Bono post-Zoo TV (and especially post-PopMart, which is to say, this decade's Bono) is that the old (younger) Bono appeared natural and unselfconscious onstage, whereas the newer (older) Bono appears self-conscious onstage. That is, Bono of the 2000s does poses, worries about looking cool, shouts at the audience in the same way every night during guitar solos, and appears to calculate every little move for maximum, age-defying, dramatic effect.
It was actually a sad day for U2 when Bono discovered 'cool' (sometime around 1988), because he was so good at being uncool that when he tries to be cool, he not only fails (which would be fine if he weren't trying), but he fails spectacularly the more he tries (which is bad, because he's trying).
All verbal silliness aside, it has been a bit of a dilemma for him onstage since the "irony" went out of U2's stage performance. He doesn't want to make people think he's the old Bono from the 80s anymore, but he also doesn't want to be super-ironic Bono. He therefore seems to try being "cooler" as his 2000s' approach, but obviously he can't pull that off.
These are all reasons why Bono deserves more money than Larry, heh, heh...
