I feel that the unreleased os2008 works fine. I flashed just before I traveled to LA and the os was very stable, movies worked great in ukmp, as did fbreader. The battery life is incredible, as I only had to charge it once in the entire 8 days I was there. BT networking was great for browsing in the car and looking up stuff. All in all it was a great experience and I didn't even take my laptop (dell latitude d420) out the entire time I was there.
