Firstly: IMHO your post did not add a lot of value to the topic in discussion. The point is not to make a list of what you like in the existing device. The general idea was to collect the possible improvements.

Secondly: I don't think that you would like to use the up and down arrow on my device which has a Scandinavian keyboard and you need to keep the "blue arrow" on the left side of the keyboard pressed in order to use the up and down arrow (which are the same two buttons as the left and right arrow)
