The only "object" I generally use is DX Weather. The rest is just eye candy, though I have to admit, they're fun to look at. What I DO love about DX are the desktop themes. Most notably, and usable for me are gef's themes and Phoon's themes. Gef's are generally more usable for me, because the menu stays put in the sidebar, whereas Phoon's pop up elsewhere on the window.
With those themes configured for the programs I use most frequently, I almost never have to go searching through the windoze program menu, which is, in my opinion a pain in the a**. However, just to keep things easily accessible, I configure the theme to show the object bar, then configure the bar to "hide" when not in use.
One thing for sure, DX was really confusing and troublesome at first. I can't tell you how many times I've had to reboot my computer, until I figured out that I didn't need to do that. Essentially, learning all the Wincustomize stuff has also taught me so much about configuring computers, in general. And that, in and of itself, is excellent. How many times have you had to show someone at work or in your family how to access stuff, because in general, MS Windows has so many hidden and imbedded stuff, that most users just never, ever know about it? Every day, I learn something new, and I ain't no geek. But, I suppose geekiness is a relative thing.
