Every since the Master Collection was announced by Adobe, I told myself that I just HAD to have it, and now, I do! Every application that comes with this master suite, I will try to learn and use to their fullest extent. I've been meaning to get into video editing and production for the longest time, as I have a high end HDR camera at my disposal. I think After Effects would be pretty awesome alongside video and flash animations.
There are a lot of new features in the whole CS3 suite that have intrigued me to make the grand purchase. Just the fact alone that I can work so easily between all the applications seamlessly makes it worth it for me. On top of that, performance improvements from CS2 to CS3 running on Intel Macs is great, too!
