I haven't seen anything on the privacy screen protectors on here so i thought i'd add one. I love my big dx screen but i don't want everyone else seeing it. I tried the privacy screen protectors on ebay and they suk! Their too thick so you can't even use your phone. I got the clarivue privacy screen protector and it's awesome! I can see perfectly but the person beside me only sees smudges. Yes it works in both landscape and portrait. It doesn't leave any finger smudges at all. I even got a follow up email from them asking me how i liked it. So great customer service and an even better product.
