Ever since learning about the IT's, I have been wondering if anything about the core memory components can be expanded. Since I have seen no post asking this directly (yes, I searched, although the ultimate search string may have eluded me..) I ask, wonder: Can the 128MB RAM or 256MB "internal memory" be enhanced by the user? This is but one cryptic aspect of these devices - cryptic in that there is very little listed, discussed, or clearly sealed off. It seems a closed door, but can someone put a nail in this for me.

Thanks.
