You can make money with Amiga, if you want. The guy who uses an Amiga in a bowling hall surely is making profit. Article writers does not need much more than a text editor, so Amiga will be very good for this task as well. Pixel artists have many great Amiga tools at hand.
If someone says that you can't make money with the Amiga, then he is either disabled or lacks imagination.
I make money with my Amiga, but I am not telling how, because other Amigans may try to take my profit.
