err, i think one is confusing ram and flash/storage...

its storage will be a 8GB microsd card (the place where the os and software will go). and as its a microsd, one will be able to expand that in the future (probably by booting from a usb stick and mirroring the current sd over to a new one, unless one wants to do a full reinstall).

the more i look at this thing, the more it seems like a geek dream...
