Glare is subjective. I find the 600 screen to be perfectly readable in almost any situation.
I've used it:
- At home, under CFL bulbs.
- At home, under incandescent.
- At school, under some form of metal halide.
- At school, under high bay fluorescent.
- In natural sunlight.
In all circumstances, any amount of glare was negated by a slight angling of the screen.
As for a screen protector, check
this thread for some info, particularly page 4.
