Provides more "grip" for the pen. Without the etching a pen would feel "slippery" on the smooth glass surface.
Like other anti-glare treatments, etched glass can produce an effect called anti-glare sparkle which is a "rainbow noise" effect. Depending on the tablet there will be a little or lot of this sparkle. Learn more here: Anti-glare sparkle.
