IIRC people whinged when Win95 came out.
Just because it was all different and strange. For people that have been working with Macs for many years, it's understandable that they wouldn't want to change.
I was only an occasional Mac-user before I bought my iBook - my Duo230, Mac SE, and LCIII didn't exactly have enough power to be considered useful for everyday machines. (I acquired them over the last three or four years). So, I wasn't totally into the pre-Aqua interface. It was convenient, did the job, the application-switching menu was kinda groovy, though I missed the at-a-glance view of what applications were running, which you had in Win95. And you have it in Aqua. So I'm happy.
Took me about two hours of playing with OS9 on the iBook before I booted into OSX. And have pretty much stayed there ever since. It's not perfect, it does need work, but even as it is I'm quite fond.
On and on and on and on,
and on and on and on goes John.
