Thanks to all!,
Appreciated Neal ManBear and Djohnston, those were very clear explanations, I got it now. Linux is really powerful!, those meta-packages are fantastic!, I even saw a task-lamp there, so I installed and tested:
3.- LXDE (I like it, light and powerful)
Kontact is a standard PIN, but it lacks many things that I need. I need a software to handled Brainstorms, Strategies, Goals and its corresponding tasks in time and budget, coordinated with the calendar, from the perspective of a single man not a project management software for workgroups. It also lacks of a key feature for me: to have Outlined Notes with a powerful search.
So I uninstalled everything except Openbox and LXDE and I am running LXDE by default.
5.- MyliveCD is fantastic!, it makes me feel relaxed because now I have my Host in a Live CD, so I can install it in any new machine very fast, with everything, then copy the VMs from backups, USB HD or NAS, so a work of a couple of hours not a week or two, like before.
One mystery I got with Mylivecd is this:
5.1 mylivecd --nodir=^/home/joejac/VirtualBoxVMs,^/home/joejac/tmp PCLOSjac17Nov11.iso
It gives a 1.7GB ISO that do not fit in my mini DVD R/W which is 1.4GB
5.2 mylivecd --nodir=^/home/joejac/VirtualBoxVMs,^/home/joejac/tmp,^/home/joejac/.mozilla PCLOSjac17Nov11.iso
It gives an 842MB which is ideal, but at the expenses of taking out .mozilla, the strange thing is that .mozilla directory is about 67MB only, I do not understand where the additional +800MB in the first ISO came from.
Now I see how powerful the command line can be. It is very nice to point and click, but it is better to have flexibility, performance, reliability and security and these requires time, study and practice of PCLinuxOS, thanks for pointing me in the right direction.
