Pros
Pro Cloud sync
Users need to create an account for Things Cloud (the account can be created from any device). Once signed up, cloud sync will be active, and you’ll have to login on all of your devices to complete setup. From that point on, syncing happens in the background. It is invisible and always reliable.

At the beginning of every day, a yellow box appears at the top of the Today section, displaying all tasks scheduled for this day. You can investigate them, and then decide which ones you’ll have for that day and which one you’d rather want to delay.

Cons
Con Expensive if you buy apps for Mac, iPhone and iPad (all sold separately)
As at May 2016 if buying all three apps it cost $80! That said there is no annual subscription and I've been using Things for years and have only paid once so far.
Con Poor calendar view
Could be more convenient with calendar interaction. Not an ordinary approach for visual people, if you want to see all the calendar events in the familiar format.
Con No file attachment available
Con No supported time based/location based alarms
Other apps have these abilities, and they are very useful. Especially for a $10 app, it would be great to include these premium features.
Con Windows version startup too slow, on 1st time use
8G RAM, SSD, ToDoList Starting always takes 3-5 seconds to load, but if you go to settings and tune it to start with Windows and to minimize instead of closing, it will be instantaneous next time you use it.
Con Android app is in early stages still
Only the Windows version is fully-featured. The Android app is still in early development.
