Well, you have to take those screenshots with a grain of salt. Imagine the screenshots CBM might have displaysed for 1.3, 2.04, etc. They'd have been promoting their default colors, default icons, etc., rather than the mileage we Amiga users ended up getting out of those OS's after fully customizing to our personal likes and dislikes.
This is one of the things that I have always appreciated about Amiga OS's...the ability to customize it so completely that you care scarcely identify what system you are even on. Especially now, if you browse the Aminet WB pics which are as state-of-the-art as any OS in existance (past or present!)
All hail Amiga!
