Lots of tools that don't do as much as I was expecting – Orby Widgets - To Make Notification Center Even More Useful Review

The short of it is, good selection of tools and a wide variety, although they are not as intuitive as I would have predicted. For instance, the quick call option does not show your contact list as it would in the contacts app, the network widget just shows a Mac and IP but no more info or of any other device, and most upsetting the app launcher does not let you launch any app you own or have on your device, just the ones they want to make available.
