Cons
Con Not many packages
Although Rudix is in development since 2005, there's a distinct lack of packages available. This limits the usefulness of the package manager for the user.
Con Lacks man files for installed packages
The man files for tools are not installed with the binaries.
Con Not sandboxed
Binaries go directly to /usr/bin, so they are not sandboxed.

Con Doesn't have everything
Conda is relatively new and has a smaller user-base, so the set of packages available is limited.
Con No way to resume downloads
Any download that is canceled or interrupted will have to be started over from the beginning as there is no built in solution for resuming downloads.
