I've got the zagg invisibleshield, the first screen protector I've used. When I touch the screen it feels slightly sticky, and when I scroll my finger judders rather than glides smoothly. Are there any brands that aren't like this?
The PowerSupport anitglare for the iPad makes the surface smooth..... smoother than the original glass surface (and a baby's butt). I would imagine that their iPhone version would do the same.....
