Lets not forget that. Its all about software, NOT hardware.
Some people define Amiga as "everything that has a Paula chip". So not everyone would share this view. Actually it is quite modern, because in a world that is dominated by GHz and virtual machines you can indded claim it is all about software.
To reach a certail level of cleanness and performance however, your software has to be written with the hardware in mind. You have to avoid things it can“t do very well and make heavy use of its benefits. At least this is what Amiga programmers tried to do.
