The reasons for running an Amiga, be it classic or forthcomming, seem pretty straightforward to me... They're pretty much the same reasons so many geeks have turned to Linux.
Many geeks have grown tired of the way M$ has grown from a company that sold a pretty good OS and a few games, into a company that wants to provide a "solution" to every computer user's needs. Somehow their products end up becomming and industry standard...
AND NOW THE GEEKS ARE BORED!
Some of us not only reject M$ software, but have grown to reject the entire platform, hardware included. But what choice is there? Apple? Go from one idiot box to another (no offence, I do own one myself)?
With Amiga, we have a chance to start over... Our way. We liked it before, we like it now, and we'll make it to our liking in the future.
What's an Amiga? A Prowler on a highway packed with Civics!
