Hopefully treating my self to the Ipad mini 4 as a replacement for my Nexus 7 - Despite my Nexus having an anti glare screen, I continue to have problems on our brighter / sunny days and I'm hoping the Ipad might help with this problem. If I get it, is an anti glare screen going to help or might it affect the 'touch screen' controlling and if not, which anti glare screen ?
