I find it extremely fascinating what the landscape of computing would look like today if Commodore had survived.
Microsoft of course would still be going with Windows and I think the current crop of PC's etc of what we have today would still be the same in a large way.
If the Amiga had lived on it may have lived on in high-end video studios. But then again, maybe not. Look at what happened to Silicon Graphics
I think C= Amiga today would be a flagship leader in gaming. It would have a hard time in the office/infrastructure market with what we have today imo...
Who knows though, but the Amiga was truly groundbreaking for its time and still is in a way with what it can do with so little.
