Looking at a comparison between the two Verse Pro 6" 16GB models, either Blue or Black/Red, I see a lot of differences that I don't understand. For example, the screen: Frontlight for the Blue, and touchscreen for the other. What's even more disturbing is that in terms of document, audio and image formats, the Blue advertises far more than the other, even though it's 10 dollars more expensive. Can anyone explain this to me? Thanks in advance! :-)
