Yep, Joanna modded her Lenovo IdeaPad S10-2 netbook with Pixel Qi screen and made a good how-to for it.. .. and reviewed it too of course.
As I have said on my videos of it, you can get 2 more hours from 10 hour netbook or 1 more hour with the 5 hour ideapad with it's backlight off mode.. and you can use it in direct sunlight!
It's worth noting that while installing Pixel Qi screen to Ideapad is like a walk in a park, putting it to other netbooks isn't. Pixel Qi screen has 30 pin connector which is not on most netbooks, so you would need to make an adapter or custom cable and backlight off switch for it...
..which is my current plan: I'm planning of putting one to Asus Eee PC 1015N when I get one.
