You cannot compare a Model-T to a 2011 Ford Mustang. They are from different worlds. Both will get you where you want to go but certain advances have become mandatory for a reason. In the case of Operating Systems, Memory Protection and security are necessary.

2011 Ford Mustang still has a live rear axle, not a good example;)
I like to think of the Amiga more like an AC Cobra with no air bags, traction control, abs breaks, power steering, or other non essential bloat. It's bare bones and slower than some of today's cars and you can kill yourself in a jiffy but it's worth the ride

And yes, Amiga is fun the same way:)
