This is a growing problem that has it's pluses and minuses.
First, this all starts with Google locking things down more and more. Even with root, 3rd party apps can't do everything they could for us. But the OEM's are able to, however that means installing as a system app that you can't remove without root.
IMO, this is starting to approach illegal competition (think MS bundling IE prominently and making it difficult to install Netscape). Even with root, developers still can't compete on all features with Google and the OEM's. And without root it's not fair competition, at all.
