    Aww, man! I was going to comment on the Win 7 in the left hand side of the first screenshot. I have Win 7 and am running it on an 80 GB HDD. Since I skipped Vista (XP ftw!) Win 7 is amazing to me.

    I still don't feel comfortable with the fact that I need to specify a fixed file size from the start. Isn´t there a way to auto-resize the DMG like when compressing a ZIP or RAR?

    sure, but what if I need a small file to distribute on the web? Does all of this files you download are carefully measured to make a .DMG according to the files it contain?. Maybe there's an application to create them with the smallest possible size, I'll take a look around...

    In Disk Utility:

    File/New/Disk Image From folder...

    or command+shift+N

    Take a look at this to add some fancy features to your image file like a background and to hide some things.
