I have been using 7.0c for about a year now and things are going "ok" so far. What I mean by "ok" is there are a couple of little things that bother me like not having the option for "underlune" when doing text.
I have been reading online about Vegas Pro 8.0 but don't know if it's worth upgrading so I want to ask the community. What are your thoughts? Is it worth the $250?
