A few thoughts on ObjectDock (FWIW, IMHO, etc.):
I installed it on my dekstop computer at work yesterday, but I have too many icons for it to be effective. It winds up having the same function as the Quick Launch toolbar, but takes up more room. It’s definitely cool-looking, and more customizeable than I expected, just not right for my desk. I might try it on my laptop, though, where I have far fewer icons…and where the Mac users at work are more likely to see it and go “whaaaa…??”
Currently I have it installed and working at home, where I also have far fewer desktop icons than at work. I’m not going to delete my My Computer, My Network Places, or Recycle Bin icons, though, so I can’t get a completely clean desktop. Still, it’s cleaner than it was, and I set my taskbar to ‘autohide’ so that I can still access my Start button but I don’t see the redundant taskbar the rest of the time. I like the weather docklet, too. I plan to keep using it at home for a while, and see what I think after a week or so.
Basically, my opinion is that it is fun to play with and kind of cool-looking, but it doesn’t make life easier or anything. It was free, though, so I ain’t complaining.
