Aye, the Toaster and LW and other related software was an absolute game changer for the computer industry, and absolutely instrumental in the success of the Amiga. WB and the rest of the OS itself facilitated the Toaster in a way that worked so damned well, I dare say the Toaster wouldn't have been possible at that time on any other platform, at least not in such a user friendly way. The kickass games didn't hurt, and either did all the cool productivity apps, but the Toaster was a real biggie in promoting the computer as a whole.
