Hi. First time poster here. I too am typing from my 9300 which I got yesterday. My screen part number is K9922 and the description says it's a Samsung.
It does have a slight "sparkle". It looks like a dusty CRT screen. It's only noticeable on light backgrounds and it is not too pronounced.
The brightness is good, but the richness of the colors is lacking a little, at least when compared to my basic desktop Samsung 710n monitor. Compared to my wife's T42, it looks much better.
Mine has some backlight leakage, and just like someone mentioned, it's especially noticeable on the bottom portion of the screen. There is some on the sides too. You can seen this on really dark (almost black) backgrounds.
