I had an InvisibleSHIELD for my old Blackberry and I loved it for its durability. I was thinking about putting one on my new Sprint HTC Hero, but I remember it having kind of a tacky, gummy, sticky feel to it...kind of resistant to sliding your finger over it smoothly. That doesn't matter to me whatsoever when I'm not using a touch screen, but has anyone used one on a Hero? I don't want to buy one and find out it makes my phone harder to use. Specifically, I've just gotten pretty good at using SlideIT (wish I could try Swype), and I have a feeling that with an InvisibleSHIELD it will be much harder to accurately move my finger to the right spots on the screen at the right times. Has anyone had any experience with this?
