This shows the tricky position Apple is in. They are a progressive minded company with a user base that has grown to also include many traditional / conservative users who don't like change and maybe have little or no interest in the potential of new technology. Difficult to keep everyone happy. Apple has been a bit more responsive lately making some small compromises so I wouldn't be surprised if 10.10.1 improves some of the rough edges of the new UI on non-Retina displays.
