I still hear this kind of stuff all the time. When dealing with clients who I am building applications for it's possible to explain the differences and have them accept those differences. However, if my clients still don't know why things look different in different browser, then it's pretty likely that most other non-technical people don't understand the differences either and I won't have the opportunity to explain things to them. Also, there are a lot of people that still don't even know what browser they use, so any explanation of browser differences is still a few conversations in the future.
