Lots of promises were kept -- delayed perhaps, but kept. We were promised PCI. Delivered. Promised drivers for PCI cards. Delivered. Promised USB. Delivered. Promised PPC. Delivered. Promised OS3.5. Delivered. 3.9? Delivered. Bug fixes (bb1 and 2). Delivered. Promised G4/G5 acceleration + AGP. We'll see.
They have nothing to do with Amiga Inc. PCI busboards, USB, PPC accelerators and all other hardware was done by other companies. 3.5 and 3.9 was not developed by Amiga Inc but under license by Haage & Partner.
Amiga Inc did nothing else except made party pack promises where AmigaDE SDK purchaser gets $50 discount from OS4. Or something like that, nobody remembers it anymore and new Amiga Inc is not going to honour promised discounts of old Amiga Inc.
If you look into history you will find out that Amiga Inc was sold to KMOS few years ago and KMOS later on renamed themselves to Amiga Inc.
