There's been a lot of discussion lately about the new Dell Dock http://support.dell.com/support/downloads/download.aspx?c=us&l=en&s=gen&releaseid=R186613&SystemID=STUDIO1536&servicetag=&os=WLH&osl=en&deviceid=17533&devlib=0&typecnt=0&vercnt=1&catid=-1&impid=-1&formatcnt=1&libid=25&fileid=262915
. This new dock was designed by Stardock for Dell.
There are a lot of cool new features and levels of functionality in the Dell Dock (like categories, which are somewhat like stacks or flyout menus), which I hope Stardock will include in the next version ObjectDock Plus. In my opinion, however, OD+ is much more flexible. For instance, one can add docklets to OD+, but seemingly cannot do this on the Dell Dock. Also, OD+ is much easier to skin. It is possible to skin the Dell Dock, but it is nowhere near as "skinner friendly" as OD+.
Still, it would be worth your while to download and try the Dell Dock. If Stardock ever decided to marry the Dell Dock with OD+... oh my! would it be a wonderful thing!
