As groovy (and potentially great) as Vegas is, I'm not 
really sure what it's advantages are over a good audio 
sequencer like Cubase. In fact, most audio sequencers 
handle both audio AND midi in a mulitrack format similar to 
Vegas, and have fairly extensive editing functions. When 
you factor in a robust and OPEN plugin system that inspires 
3rd party innovation, score creation, and in the case of 
many sequencers, a much lower price, Vegas leaves me a 
little flat. 
Don't get me wrong, what Vegas does, it does good, but it's 
not revolutionary and it's narrow focus fits a lower price 
point. Don't freak, just an opinion. Now y'all can tell me 
what a moron I am ;)
