Thanks a lot for all your nice advices,
I do not like dual boot, I prefer this, I installed in the compromised Core i7 machine:
1.- Full erase of the hard disk and encryption as per this nice and easy tutorial:
http://pclosmag.com/html/Issues/201108/page19.html2.- I Installed
OpenBox as Host, I did not like it, I felt in love with LXDE at first sight, but OpenBox said in its download page: "Openbox is an extremely fast-performing and energy-saving desktop environment. ..OpenBox uses less CPU and less RAM than other environments...It is also well-suited to modern computers with fast CPUs and lots of RAM." But I do not notice much the difference in speed compared with LXDE, and OpenBox affected severely my limited sleeping hours.
2.1 Although I can modify menu.xml with Geany (nice editor) no luck to Hibernate the PC or Lock the user. I wonder if I did a good choice or if I can upgrade OpenBox to LXDE without re-instalation, or I need more hours of no sleep investigating how to tune up OpenBox

3.- I Installed VBox VM with Win7 CD from my new Dual Core, I plan to enter the Win 7 key that is in a sticker below the Core i7, hope it works. This would be for those programs that I am not able to find a replacement or it do not run under wine yet.
4.- I Installed VBox VM with LXDE for the rest of my applications and replacements.
5.- But for me
it is very important to have a full Organizer, to store my banks movements and passwords, do brainstorming, write, planning, tasks, to-dos, agenda, phones, concept mapping, notes in an outline organized and consistent way in one GUI, and I have not seen a remote replacement for this Windows Organizer, this
is the Core Control Center of my life activities and I would like it running in my
LXDE VM, not in Windows 7:

if someone knows of something close to Do Organizer that now is called Harmony.
5.2 I was told it might run on wine 1.3.32 but I am not able to test because it is not in the repositories, and I am not prepared to compile anything yet and to break my Linux installation, please see:

I think it should be simple.
