Yeah. But I guess the distinction is quite relevant with things more complex than a hammer. For example, you are not legally entitled to return a camera because you thought it could shoot in 3D and it couldn't, unless the advertising falsely claimed that. The seller might accept a return, but they're not obliged to. The EULA thing is sort of on the edge of that. Many (most?) devices come with EULAs these days. So you could make an argument that the buyer can't reasonably expect there to not be additional terms that they must accept before using it. I don't really find that argument very compelling, though, if the terms are not available to the buyer at the point of sale.
