It works well for me. I use 7 screens to organize my apps. Nice transition from screen to screen with the cube effect. Never sluggish and no force closes for me.
I'm a fan. With the exception of one update several days ago that created problems (and was promptly replaced), I've had no FC's of consequence and prefer it to both the default home screen and home++. (Haven't tried others.)
The seven home screens revolve in either direction. The application dock enables access to a variety of user selected apps in a 4x1 space. Numerous skins are available. The "cube" effect is attractive and a double press of the home button takes one from an app to the last screen shown and then to the "startup" home screen.
