A regular desktop user does not want bleeding-edge software; he will do just fine with last year's VLC. (A notable exception being the web browser.)

The priority for a regular desktop user is a nicely integrated system, and that is something that ISVs cannot deliver because they don't know what to integrate with.

Except for the security stuff, i think many would be quite happy with last years Firefox, Chrome or even IE.
