When you put it that way, it is more forgiveable. I was going to say how it's funny that backwards compatibility was never that big a deal until the PS2 came along, but then I got to thinking about the 7800 and the 5200's adaptor for the 2600. Somewhat similarly there were the 2600 adaptors for Coleco and Intellivision. Sega Genesis had the SMS attachment. Granted, except for the 7800, none of those were out of the box compatible, and even that skipped a console generation.
To me, backwards compatibility isn't that much of an issue. I'd rather see that R&D go into making the new consoles better, and perhaps even reducing costs of the final product. Of course, this is all coming from a guy that doesn't own any console newer than an N64 and has no special insights into the inner-workings of the gaming industry. So maybe I'll just shut my big mouth.
