I hate to tell you this, but with or without a anti glare screen protector, your screen is still going to be hard to read in outside light.

It is the screen technology that makes it hard to read.  Since your screen is backlit, any intense amount of light hitting the screen (i.e. the sun outside), is going to make it very hard to see your screen.
