I think .info is brilliant, since it allows me to set different tooltypes and default tool for every single file, and not just for group of files, and it is done in an easy to understand and editable way. I'm quite confident that you cannot even do this on Windows.
Seriously, all the people who think Windows does everything so much better should just stick to Windows, and not whine about doing AmigaOS more like Windows - or you could just use Linux - KDE and Gnome are both busy doing everything as similar as Windows as they can :p
