WhatsApp cannot be used by people without a smart phone with an active cell plan.

Con Proprietary
Not open source.
Con Hard to migrate history cross platform

To use your computer to send messages your phone must be on with a consistent data connection.
Con Single device

Messages are not stored on WhatsApp server for privacy and security reasons.
Con Limitation on shareable file sizes
WhatsApp now allows users to share files of any type, but there is still a 16 MB size limit.
