I have a Jetbook and yes, the screen is excellent outdoors and in sunlight. No problems at all.
I also have a Sony and I do like the whiter screen of the eink.
have the ebookwise with the backlit LCD screen and the reflection on the screen in sunlight is noticeable. I like it for its bigger page-turn buttons and its backlight in darker situations.
The Sony is so elegant and feels so well-made, and as I said I like the whiter screen and the beautiful look of the words on the 'page'.
And the jetbook I love because - it's just so darn lovable.
