I have to say I’m very satisfied with Adobe's presentation of the new CS4. Here are a few main reasons from a usability standpoint:
- Adobe focused on workflow and user experience.
- They kept most of great Macromedia GUI innovations and greatly developed some of them further.
- FireWorks has become a full member of CS family.
- PDF workflow is greatly improved and has become really usable compared to previous versions.
- Unified interfaces.
- Great improvements in usability of AI and ID tools. Now there is no need to go through few windows to change opacity or gradient for instance.
- I generally like updates. Fresh wave in daily routines or interactions with the computer.
