The ETI-2 by ebooktechnologies  appears to be the exact same device. If so, does anyone have any info on updating the old REB1100 firmware to the new ETI-2 firmware?
 upgrade an 1100 to an 1150
While the two units look the same the screen is very different. The 1150 is a 4 layer grayscale screen while the 1100 is a monochrome (black/white) screen. I doubt there is any way to upgrade it however an email to eBook Technologies, Inc. should give you the full info on this. DaleDe 16:37, 7 August 2008 (EDT)
