It doesn't launch as another app in your dock, instead it sits in your (albeit overcrowded) menu bar, and provides only a few sparse settings - the background color to use, whether to make the backdrop opaque (so you can see the desktop underneath it), whether it should start when you log in or activate automatically, and what key shortcut should activate/deactivate it.

...Having only used it for a short while I can't proclaim how it has saved me x hours per week or saved the lives of thirty-three cats, but even after my limited use it looks to be an app well worth using.

Microsoft's Windows Vista has become the most hated release of Windows yet - missing features (hardware accelerated GUI, database-based filing system, smart search engine, etc), irritating features (the security requesters), confusing number of editions ( seven available in the USA, two more in Europe), confusing graphics system (DirectX 10.0, incompatible with the upcoming DX10.1, slower than DX9), and more.

...So, to set the record straight, Linux kernel hacker Robert Love responded with a wonderful reply that cut Mr Russinovich's reply to shreds, simply saying that Vista is poorly designed and that Linux doesn't suffer from the same stupid bugs.
