'Kind of sad to have to try "fostering" the act of reading. I say let them in the dark.
What pisses me off is that Amazon is gradually adding simple features to the Kindle DX when it could have provided it all from the start.
Things like highlighting, adding notes, browsing bookmarks, reading out-loud... wait until Kindle DX 2nd generation and you will understand! Just add those features and I won't need printed editions anymore (except for reference books)!
I think the ribbon is actually a great idea and a great way of organizing buttons - provided that someone tell you that you are supposed to be moving your eyes across each block of button's name on the bottom, NOT LOOKING AT THE BUTTONS THEMSELVES! As - I believe - most people would find it counter-intuitive to look to the bottom of the ribbon (button-group name) first instead of the top (actual buttons), it was probably very unfortunate to position them that way.
Also, I use to think a ribbon should carry mostly buttons with icons, but looking at that Open Office ribbon with text-only buttons - hmm, it may work fine...
