Witness Bodum.
Two sites, "Online Shop" and "Company Site".
One uses frames, the other flash.
Neither is "deep-link" friendly.
But they sell consumer products. I have no ability to send a link to someone and say "check out this cool bodum product", in fact Bodum also has no ability to do this. If you drill down into their crappy flash piece on the "company site" and get to a product, they provide a link to the same product in their "online shop", however it doesn't work (I'm hoping that's due to oversight and a redesign or something).
It aggravates me. Especially when it's a company that touts, "give up bad design for good", which seems only to apply to coffee and tea paraphernalia, and not their own web presence.
