Query: Improvements needed until I purchase Kindle

I've been looking at Kindle for awhile, but I won't purchase it until at least two specific upgrades are added. 1) The screen should be touch interactive to allow for a pointer device to highlight words/passages. This would be similar to note-taking that you could store either within another file on the Kindle, or at least refer back to through a bookmark. 2) This device could truly be revolutionary if there were either an internal dictionary or web-linked dictionary (e.g. via m-w.com) that would allow you to double click the world to grab its definition.Any other users think these would be good additions? Bezos - are you listening?
