seems all this "amiga" is some kind of charity excercise. but a trusty charity demands transparency. anything else is plain silly.
So, back to the topic name - it says SAM 460 - poor performance, high price
Okay, all the Amiga hardware released after the Amiga 3000, had poor performance and high price. This is nothing new. The Amiga 3000 was the last model that had decent price/performance ratio and even was used as a UNIX workstation (Amiga3000UX), because similar UNIX configurations from other vendors were much more expensive. All the later Amiga models where with poor performance and high price.
Beating own chest, trying to prove something that everyone knows, 20 years after the release of the Amiga CDTV and the Amiga 600, which were disasters and disappointment and already expensive with poor performance is plain silly.
So far the charity exercise, did not help the Commodore survive. All the persons who still use Amiga, know that the hardware is expensive with poor performance, but it does not stop them from buying it.
On the other hand - Mac hardware is also with poor performance and high price, compared to the PC hardware. Be it brand new or second hand.
