Not Garbage. Default configuration is not optimal, however.
I use it all the time on Windows XP to run Ubuntu.
Initially, I did have a few problems because I didn't have Ubuntu or Virtualbox configured correctly. Also, I wasn't using 'VBOXADDITIONS,' which actually are extremely useful and important.
Some quick googling fixed my problems, in any case and I don't have any problems with it anymore.
