HiToro was good at inventing technology. It was not so good at upgrading it though.
I don't really know about that. I've seen interviews with Jay where he was talking about upgrades the Amiga needed...
If you look at Jay at Atari, he went from TIA to Antic/CTIA and then to the Amiga..
Yes, those are different systems, but that's because the place he was working was looking for different systems.
You can't blame Commodore for buying the Amiga and trying to milk the same basic design for years, as they did with the C64 (Well, you can blame them, but..), but I don't think you should draw the conclusion that he (and when I say "he", we're talking Jay and his team) wouldn't have been able to work on upgrades...
I think they probably could have...
If they would have had enough money to continue (some mythological group of different dentists with lots of money to save them..), I think the team could have designed great upgrades faster than Commodore did.
That said, you need distribution and marketing to sell computers..
Without Commodore, the price would most likely have been higher and it would have been harder to get an Amiga...
I think it's likely that Amiga wouldn't have made it as a company if they had just been given more money...
A better idea would have been, what if someone ELSE stepped forward who also had distribution and marketing...
Say, Tandy or even... (should I say it???) Microsoft.. (Hey, they've tried hardware several times over the years..)
Maybe IBM? (Don't laugh, they were just looking into OS/2 in 85.. Would have been an interesting idea and a way for them to get back at Microsoft..)
