I've spent more than a month working with Adobe Creative Suite 4 Master Collection. I'm impressed. It pushes the envelope again with new tools and enhancements that will save a lot of time.
The latest Adobe Creative Suite 4 for Mac OS X and Windows is now shipping in all its flavors: Design Premium ($1799), Web Premium ($1699), Production Premium ($1699), and $2499 for the Adobe Creative Suite 4 Master Collection. I can't wait to try the new GPU-based acceleration.
