The knock on backwards compatibility isn't a complaint about backwards compatibility, per se. It's about how so much of the OS is held back due to that support for old software. The trash menus I'm referring to, while the language is a bit strong, are how there is no unified design throughout the OS. It reeks of implementing new features halfway and rushing it out, since most of what the user sees is now "new".
