well my mother has called my Mp3 players (last one, Iaudio X5, which i bought maybe 3 years ago) has always been an IPod. its not an ipod, but its an Ipod none the less.
and quite a few times people have asked me, Hey is that a Kindle. I say know. its like a Kindle.
I would call my 700 an Ereader before i would call it a Kindle.
