Cons
Con Steep learning curve
Drupal is not easy to get into and out of the box doesn't offer much. To get Drupal doing what you want it to, modules are required. To get modules, an understanding of how Drupal works is required. And that takes time.
Con High resource consumption
A more complex Dupal installation can easily exhaust 256 MB of RAM with only one or two visitors.
Con Documentation is a joke
With currently 3 different version of drupal in active use, and at that constantly changing capibilities within 2 of those, it means that when you look for documentation is if often for a different version that you are running and in addition is not at all easy to consume. Often the info you need is in comment #100 of a thread.
Con Lacks good free modules and themes
Most good third-party modules and themes are costly.
