DR Michael Shayne - Since no one really seemed to answer the question...
I asked BK about what size iPod he got, I can't remember how many GIGs he got, but he got the "smaller" one of the standard sized iPods.
As for ditching your CD collection.... Well, first you have to transfer your CD collection to the iPod, so... And, then, god forbid, you lose your iPod, or something happens to it... and you had already ditched your CDs...
Most people I know still keep their CDs. The main purpose of the iPod is portability. It cannot replace CDs since it will need a source for the songs it stores - and, yes, you can download from iTunes and other places, but not everything is online.
