...but I guess you can never please a technology junkie.
I did the upgrade. No issues at all. So the book cover does not display! It's not like I have my KOBO hanging on the wall like a photo
I am glad it shuts off, as I found my battery life was much improved when I did that. As far as those who lament about the it taking "forever" to boot up - I just timed it and it takes EXACTLY 34 seconds from a cold start - hardly an eternity.
Perhaps if people devoted less energy to whining and directed it into something more productive the world would be a better place. I mean, I know there have been some issues, but there are two Kobo's in my house, and I think they are about the greatest thing to come along since sliced bread.
And you can always go back to dead trees.
