Glad to hear the covers are coming back with the option in the next firmware. I understand that people dont read as a general rule (anyone who has worked in IT support realises this).
Personally I have no problem with the boot up time and the sleep times that have been set. But then again when I sit down to read I'm gonna be reading for a while (i.e 15 mins) and I generally read so fast that I'm not more than 15 mins per page
