While poking around, I did not see any higher capacity batteries. I wasn't looking for them, though, so maybe there are!
Anyways, so I went and took some pictures. As a disclaimer before I post these pictures and you're horribly disgusted and never consider Fujitsu again, the camera comes close, but does not accurately represent real life
It focuses on the reflection in the screen, so it shows up sharper. Generally the reflections are less noticable then the pictures make them out to be.
Also, I am happy with the screen. I have used it in a variety of conditions, sometimes in the daylight in the car. I have not had a problem with glare at ALL. I only notice it if I look for it.
Anyways, without much more fujitsu defending, here's the pictures. I tried to take one of a black and one of a white screen to show the difference.
This is a shot of the worst case scenario indoors. A very bright background compared to the rest of the room, right behind your screen:
Here is a pic in a very bright room (lit by daylight):
here is the worst case scenario. outdoors where everything is bright :P
inside in a normally lit room (still daylight, but the sun is setting :P)
inside a darker room
sorry for some blurry pictures. I did not use flash and I was too lazy to use the tripod.
as you can see, in normal conditions its not very noticable. Even outdoors in bright daylight, if the screen isn't pure black, its not as noticeable.
If you want any more "scenarios" don't hesitate to ask. I'll try when its day again :P
I wish these pictures were more of a representative of real life so you can really see, but this is as good as I can get
