Thanks Fred for your advice! anyway, for the time being, I made up my mind and installed the gnome flavour of Mint. I am a KDE fan from years, but I am also quite curious to explore "the other side", so I think it's a good thing to have KDE (kubuntu) on the laptop and Gnome (mint) on desktop...
In passing, installation in this new machine (an intel quadcore, 4 Gbyte RAM, 2x500 Gb HD) went very fast and fine! Mint rocks: IMHO, the best desktop distro in this moment !
