Pros
Pro Can recognize music
You can ask Cortana what music is playing and she will attempt to identify it.
Pro Will let you know when artists you're interested in play in your area
Cortana monitors your Bing search history, social network actions, music played, etc to find out what are your favorite artists and will let you know if they plan to play in your area.
Pro It's reliable, fast and quick
It just works...always. It's fast and quick, which can save you thousands of hours.
Pro Very configurable
You can set all sorts of things from size of database to size of individual clips, types of objects to copy/paste, which hotkeys to use etc.
Pro Scriptable clips
Clips can be used/changed with scripts during copy or paste.
Cons
Con Functionality is limited on non-Windows devices
While Cortana is available on Android and iOS, certain features on those operating systems are either limited or non-existant. For example, there's no hands-free voice activation on iOS, and on Android it's only available on the homescreen and nowhere else, etc.
Con Uninstaller removes nothing
After uninstalling removal of almost every file manually from different directories is still necessary since the actual uninstaller only displays "other files still remain".
Con Minimizes after each paste
You have to activate it twice to paste twice.
Con Does not support HDPI displays
On high DPI/resolution displays, the UI is very small. Practically unusable.
Con RTF bug is still present in latest Beta version
You can turn on the option to draw RTF text in the clip list, but it no longer works in Windows 10 Ditto (64bit), and the latest Beta version available today - which claims to have fixed the bug - still has the same bug. It will no longer draw RTF text as-is in the clip list.
Con The UI is very confusing
Con Can't use any shortcut you wish
Anything with spacebar, windows key (that the system also uses) is not possible.
