Some quick words on it. So far, I think it's great. The screen is beautiful - bright and well-saturated. It's 4.3" diagonal, about 3.74" x 2.16" (16x9). I've loaded music, pics, and videos (DVD ripped to .avi). I tried the CF download and it is fast. Not supporting RAW is a bummer but I can shoot RAW+JPEG. I was surprised by the viewing quality - I thought the screen might be too small for good viewing but it isn't. As for video, The Big Lebowski looks and sounds great - it is definitely watchable (or can be viewed on TV via supplied cables). Sound is excellent - I use Shure E3c sound isolating earphones. The one complaint is the rocker navigation switch - the upper part is too close to the menu selection button.
So just a quicky here - post any questions and I'll be glad to answer. In the end I am very happy with this purchase, no regrets.
