Okay, the dead horse has been beaten, BUT! I have one more smack to give it. Here's another reason why there's a need for a history panel...
Sometimes I have to step away from my desk and my project at an inopportune time and I do not always remember exactly where I was in the process. Frequently in PS I return to my project, click around on the history panel and get a reminder of where I am. With Illustrator, no such luck. Gotta have perfect recall or CMD-Z a bunch to try and figure out your project's evolution and where you were going with it.

Another vote for the Illustrator History Panel!
