I run mine almost exactly the same as
Talderon
I do have a screen protector on but it never said anything about anti-glare or sun resistant or super powers.
I can see my screen in direct sun light but it is washed out, which is normal imo.
People compare it to the iPhone, its almost exactly the same. I had a 3G and a 3GS and both were similar in direct sun light.
In fact, any phone I've ever seen with an oversized colour display is washed out and mostly un-readable in direct sun light.
For instance, I went out the other night and the next morning was sat in the garden with friends looking at pictures we took of the night before. On both their phones the pictures were black, you had to cup your hands round it to see anything.
On my N1, everyone could see the pictures, even the dark ones in direct sun light and even commented how good the phone performed outside in the light.
