Looks like you need to redefine what you consider "useful".
It can be very frustrating and self defeating to try to make the Amiga something it isn't and can never be, but there is still much that can be done and accomplished that would be considered very useful to hundreds of remaining Amiga users (including Amithlon, AROS, MorphOS2.x & AmigaOS3.x & 4.x users). Don't lose your enthusiasm for all things Amiga by comparing it to Windows, MacOSX, or even Linux.
