- A file encoded as a 164kps OGG Vorbis and is 4 minutes long will be: (164kpsx240secs)=3.94mb

So no saving in space - as you are using the same kps per second using both codecs.

HOWEVER, using OGG Vorbis you can encode the file @ 96kps and it will sound the same (IMHO) as MP3 @ 164kps, therefore to get the SAME QUALITY music file on your system:
MP3= 3.9mb
OGG Vorbis= (240*96)=2.3mb

A saving in space of 42%

The saving comes in the ability to encode a file that will still sound the same but at a lower bitrate.

I hope that makes sense.
Wow, very detailed answer! Thanks. I still have one more question though: If an OGG file is at a lower bit rate than an MP3 how can it sound the same? What am I missing here?
