Sorry Harry, I can't understand your arguments.
To make mine very simple :

- I prefer LiveCD than LiveDVD because:
1/ faster to download
2/ faster to run
3/ benefit of LiveDVD not real
- Despite 2 releases of v5, the latest version which works on my PC is 4.x, which is a bit old considering kernel version (and all other packages)
- the concrete result is I use Mepis more than Knoppix

I think I'm not the only one to think that way, so if Linux TAG satisfaction has a bigger priority than users one, I think you are on the right track.
