@stefcep2,
You don't have to believe the "glossy brochure", just go find one of the many videos of the Lightwave10 demos to see it in action yourself.
As for all this talk about the "soul" of the Amiga (it is really silly), the only soul the Amiga has is what is put into it by the person handling the mouse and keyboard (or joystick if you like). Amiga computers and its 1.3 to 3.1, or 3.9 OS are fantastic for their time and remarkable in that they are still used today by many people for what ever reason, but they can't be seriously compared to modern hardware and OSes because they lack so much that has been created over the last 15 to 20 years.
Enjoy Amiga hardware and the OS for what it was and still is and don't try to make it into anything else. I have had as many as 25 Amiga computers at one time, so count me as one of the faithful fans, but it does not diminish my ability to realize and appreciate the strengths and uses of other hardware, software and OSes. I don't have to run down Windows, (which I really don't care for much) or MacOSX, or Linux, just to justify why I like to use Amiga computers and its OS.
Anyone trying to convince another person which hardware or OS they should use solely on its merits is wasting their time, because everyone is going to use what they prefer, no matter what anyone else says to them.
