I think .info files are absolutely brilliant. Tooltypes are great for storing and adjusting settings. You can position Amiga icons exactly where you want them and they'll never move unless you tell them to. Separate icons allow you to hide unnecessary files, reducing visual clutter throughout your drive. And if you rename a file, it will open with the program you told it to. Filename-based program association is one of the things I hate most about Windows - i.e., renaming file.jpg to file.jpg.old and then being unable to open file.jpg.old by double-clicking.
But, if you do like filename-based program association, you can configure Deficons to work that way. Can't go wrong with the Amiga's configurability.
