Some of us like the fact we can still use 20 year old hardware..and the mere fact they can be accelerated way beyond their original abilities is also one of the attractions, 20 years ago no one would have dreamed they would be capable of running PPC speeds.
If they developed those then more modern accelerators could be too...and i would just love to point out to people Hey...my 20 year old miggy is doing ok in the modern world of computing.
This is one of the many reasons people still ask why and when if possible will someone develop new accelerators...but we all know now that will never happen.
