I like they way that the Touch shows the Dictionary popup. Most Android and iOS reader apps do that as well as some of the other eInk readers. On my K3 that tiny popup window with two lines means I often have to go to the full page. Going to the full Dictionary page is slow on a K3.

I do wish Kindles would show the pronunciation in the popup window since that is often the only thing I need to look up. I'm currently reading A Distant Mirror and frequently need to look up the pronunciation of French cities and names. It is painfully slow on the K3 to go to the full Dictionary page to see the pronunciation.
