Yes I think one of Commodore's main weaknesses was concentrating too much time and money on PC clones - time and money that would have been better spent on Amiga technology.
I don't think Commodore's PC clones were ever very highly rated. It's a pity they didn't realise this sooner and focus more on the Amiga from an earlier stage.
Still it wasn't all bad under Commodore. The themed packs were a great idea - the Batpack alone helped to shift more Amigas over the Christmas '89 period than you could shake a stick at and established it as the home computer of choice in Europe.
Plus, if Atari had bought the Amiga originally, they'd have consumed it whole. There would have been no ST and hence no clash of the titans for the remainder of the 80s and early 90s - a clash that led to some truly spectacular software being developed for both machines and which made owning a home computer truly exciting. Unlike today.
