Yes, I bought my wife on for her birthday a few weeks ago; she finds it very good indeed. She can use it for reading in bed with the inbuilt light so no need to disturb me with the bedside lights. The text is very clear, adjustable in size and can be read in bright sunlight, unlike some other readers. Downloads are rapid and there's a wide range of material available.
I take your point on the user guide. The screen in b&w and colour isn't planned for a long time; so don't wait. I wish I could get the complete Pevsner series for travelling but that's not available (yet?).
