lots of good information, opinions and life-lessons here guys - thanks!
I've always used screen protectors on my phones - well always since I scratched a few of them badly. The technology has improved as much as the screens and the glass they ar emade of so if you have a long-standing rule of going bareback you might want to reconsider as many of the drawbacks of yesteryear are gone.
For perspective, the air in an ordinary house has over a million particles per cubic meter, all. Falling down to settle on your precious screen. A fair number of them are silicon, quartz, glass etc and they CAN scratch your screen. You'll know this isn't possible when every "Gorilla Glass IV" equipped phone comes with a free lifetime replacement warrantee at Corning's expense. Untill then, scratches can and will happen. This is a greater risk when using a stylus as the pressures it can exert on the screen are formidable. So scratches are always a possibility. Whether you choose to protect against a given risk is a matter of taste. Some people go a lifetime without using a condom. Others never go out without one. Choose your risks carefully ��
So FYI I decided to buy an Incipio cover and I have to admit its initial impression is excellent. It actually does go on very easily, as long as you are maniacal about cleaning every single dust speck away. I started with a cleaning with isopropyl alcohol and a tissue to get off as much surface oil as possible. Two cleanings took all of 90 seconds. Next I used the included microfiber cloth, then went over it with a magnifying glass - ok I just looked at it really closely and used a can of air to blow away any I saw. Then following the instructions, this was the first screen protector that really did go on as easily and bubble free as the video on Youtube (of an incipio protector on an iPad - grrr) showed. Five minutes later, no misalignment issues, no dust under Theo protector, and no bubbles. Simple, quick and easy! The stylus works fine with no detectable drag. In this regard alone it is superior to the Zagg protectors I love for my phone. So for me, the Incipio was the way to go. Your mileage may vary ��
