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 A bit ugly
Using puppy makes you feel like you just jumped 20 years into the past. Being that the purpose of Puppy Linux is to run or really low resource machines the software used is often on the older side, which is precisely why it has a 20 year old look.
Con No built in compositing
Being a low resource distro there is zero built in compositing for the JWM window manager. Though one can be added through a bit of work.
Con Smallest software library ever
You can barely find any precompiled packages for Puppy.
Con Not as light as it used to be
It's light, but not as light as it was 1-2 years ago.
