Yeah but because the storage is _flash memory_, I bet that refers to the storage, not the ram. For example, if you go to this page it states:
Storage 2GB*
Memory Expansion Up to 30,000 eBooks with a 32 GB SD Memory Card
and
* 1GB is available to store content (over 1,000 ebooks).
It does not state ram which is almost certainly less than what the vox has.
