I have added the EB-300 to the wiki's E-book Reader Matrix
Things we don't know include its weight and processor type.
The battery is very large (2100 mAh), but perhaps this is a lesson learned from the iLiad. 512MB (4Gb) Flash memory, is also a lot.
I find the possibility of SD3G (see post #46 above) interesting too. All these connectivity options, without mention of a web browser and without (yet) an on-line e-book partner.
