The reason to throw away the strong brand is because it's notorious for crappy standards support. A new name on the new browser might have a small psychological benefit. Maybe.

I actually laughed out loud at that one.

I don't think having a browser bundled in the OS is really a problem it's actually something that should be a part of a modern OS. In the early days of the web it was not a need, but now days you might as well say that disk defragmenting, search indexing, media players, and half a dozen other utilities don't belong in the OS either.

Imagine, back in the day, if all the DOS file manager companies complained because Windows 3.1 included it's own file manager.
