I wonder why a lot of people get Adobe Master Suite - I bet most don't even know what half of the programs are used for, or even how to use some of them (like After Effects and Premiere).
I know how to use pretty much all of them on an at least basic level! That's not to say I use all of them, there's just no other package that doesn't lack at least one of the Adobe apps I do make use of. ;o It's certainly not for everyone, though.
