I had primarily wanted Flash Professional, but the Design Premium bundle includes a lot of other awesome software. Though I was not initially a fan of Flash programming, I have developed a lot of respect for Flash and ActionScript lately. Flash has been a useful resource for me to quickly throw together tests and proof-of-concepts, especially when it comes to animation programming. As an added bonus, CS5 seems to have made coding in ActionScript a lot easier.
Of course, everything comes with a downside: it is much easier to procrastinate now that I have the software on my computer.😉 Ideally, though, it shouldn’t be too much of an issue.
