hardware question

[Becker, Rob]

I am looking to build a laptop based ogg vorbis player for my car.  Anyone have any experience with 
ogg vorbis decoders?  I'm trying to get a feel for what the minimum hardware requirements will be 
for such a project.  I've heard that it is possible although not recommended to decode mp3's with a 
pentium 75.  I have also heard that ogg vorbis may require a little less horsepower to decode.  Can 
anyone verify either of these points?  Does anyone have older laptops that might be appropriate for 
such a project available for sale?  Although a display would be nice for the initial build, I 
assume that it would be completely unnecessary for the day to day functioning of the player, so I'm 
not sure I even need a fully functioning laptop.  Any ideas, hints, tips, trick, pointers, links 
and or comments greatly appreciated.
Thanks.
Rob
