When I talk to other designers and inevitably get into arguments with them about standards, I try to get them to see it from a consumer's point of view for non-IT products.
There are a lot of non-IT products that have the same design: doors to houses, door knobs, rear-view mirrors, tires. The list goes on.
While it's fun to see a new design to a Web site/app, even as a techie I sometimes struggle with using the sexiest websites simply because the designer has changed what I perceive to be a standard usability feature. I can't imagine what Joe 6-Pack thinks when he encounters these sites.
