Sounds really cool ! I wish they'd offer SD/CF for the DXG, it's almost insane they didn't do that. Anyway, i'm waiting for mine, just ordered it and it'll take 3 to 5 weeks as an international customers. Sux to wait that long but gives me time to start sorting books which i'd like to put on it and other stuff
Btw, it might be important to think of the battery drain when using larger capacity chips and what all the extra power needed could influence other stuff. Just guessing here but i hope you keep us posted !
