So it seems to me that all examples and explanations given for the inclusion of the real-time kernel by default are to cater for the audiophiles using Ubuntu Studio as their platform. Forgive me if I'm mistaken, but isn't Ubuntu Studio focused toward 3 groups of multimedia professionals-- Audio, Video and Graphic? I don't know the technicalities or possibilities to include a kernel option upon installation, but we need to somehow give the user a choice of which kernel to use for Ubuntu Studio. I know that either can be installed/removed via Synaptic, but not everyone feels comfortable doing it via this method. My point; there really is no reason for a real-time kernel when one uses Ubuntu Studio for Video and Graphic work. So with its default inclusion, it's simply catering for 1/3 of the intended audience/users. Just my 2 cents.
