This guy highlights transparent menu's in KDE as a feature? IIRC correctly they have been available since 2005LE, and it's a KDE selling point, not a Mandriva SP. If you are going to showcase a new product/beta it's better to focus on innovation and updates, not features that have been implemented by a third party a long time ago, and by and large haven't changed much.
Aye, the main point of galaxy was to have a near unified desktop between KDE and GNOME!
