I have been using Golive since 5 extensively and when CS came out it was an extreme disappointment. This won't be noticed as much on small websites but on larger graphics and code intensive sites Golive can literally grind to a halt due to its memory consumption. And the web development computer is on a dual Xeon workstation.

Golive in my opinion has a lot of strengths but CS does little to build on that. I have had .site files corrupt and I have experienced numerous lock-ups just to name a few problems.

The CSS side is not designed efficiently at all and does not facilitate, to my expectations, speed of development.

I have been actively researching Dreamweaver as an alternative and will more than likely switch in the next few months.
