I have used the H2O for several days now and have some further thoughts to add to my initial impressions posted the other day. Overall, I really like the device but have a few minor annoyances:
1. The touch responsiveness of the screen is noticeably slower compared to my KPW2. I have also noticed that the selection of words is also slower and equivalent to my old PRS650.
2. The alignment of the touch position is off. I will search to see if there is a way to calibrate the touch alignment (reminds me of the Palm OS devices).
3. When selecting a book to open from books or collections, there is no feedback showing that a selection has been successful. This often ends up with a noticeable lag where I question if touching the screen registered. I would prefer if the title highlighted (inversed black and white) to confirm selection. This happens when typing on the keyboard so it would not be hard to implement.
4. I have the sleep cover on and put the reader in my work bag area lined with fabric covered foam (laptop section). Later I noticed a scuff mark on the bezel which is noticeable due to the finish and I have no idea how it happened. I have never had this occur on any of my ereaders since I'm pretty careful about them. Maybe I will try washing it since it's waterproof

. I guess I will need to pick up a bezel decal when they become available.
