I just bought my first ereader after reading about these devices for a couple of years. My flagship Kobo Aura H2O was returned to store for a refund the next day. It is supposed to be touchscreen but was unbelievably laggy and unresponsive making setting it it up almost impossible. I was aware of similar issues raised by users with the Aura HD but was expecting that to have been corrected. Although there is a an Expert Review on the forum for the H2O there's no way to add any comments or maybe I've missed something here?
