I just needed to write a post about the amazing case and screen protector for my Z10. I just bought and had installed the ZAGG invisibleShield. It is AMAZING! The screen quality is still amazing, and you can't even tell there is a protector on it! Also, for outer protection I chose the Casemate brushed aluminum case. It is plastic, but has survived MANY falls so far. Doesn't unclip which is what I was worried would happen. Would highly recommend these two products. Worth every penny. (or nickel, since there's no more pennies)
