I think we might be in for a bumpy ride for the next few months on further firmware release issues. As the Elipsa was not included in the 4.28.18220 version and we should expect further updates on the 2 newer devices in the short term as kobo get a larger 'test' group....

still waiting for the epub vs kepub font size issue to be fixed!!
