Con Slow development
Con Software a bit slower to launch than for other distributions
Con Forums are not very friendly
Con There is often a black screen after update
Con An upgrade breaks the system quite often
Con No USB Image writer
Con The default desktop environment is not very customizable
Maybe because it's a relatively new project still in its infancy and this may be fixed in the future, but Budgie is not very customizable. You can only change the theme and wallpaper.
Con Steep learning curve for beginners
It's a really sparse, bare-bones system, no automatic driver install for example. It can be quite hard for someone not used to Linux.
