I imagine this is why you're torn (directly from ZAGG's WEBSITE):
The precision pre-cut invisibleSHIELD applies directly to your HTC One, providing the toughest, most durable protection you will find. The invisibleSHIELD has its origins in the military, where it was used to protect high-speed helicopter blades from dust, dirt and debris.
Now you can use that same powerful technology to protect your HTC One. It is so tough that we back it with a lifetime guarantee. So, if it ever does wear or scratch, we will replace it for free, for the life of your device. And if you ever need to remove the invisibleSHIELD, no problem; it comes off clean and leaves no sticky residue.
The authentic invisibleSHIELD film features Nano-Memory technology, which is visible as a very subtle texture in the surface of the film.
Perhaps not so desirable,however,it does provide a great amount of protection,no argument there:
This superior component of the invisibleSHIELD offers four main competitive benefits:
Durability - Self-healing properties offer unbelievable resistance to scratches and damage, and will extend the life of your device
Coverage - Greater pliability and flexibility allows the invisibleSHIELD designs to cover the corners and curves of your device better than the competition.
Ease of Install - The improved pliability also facilitates easier installation
Drop Resistant - Improved grip makes it easier to hang onto your expensive gadgets
Glare Reduction - The invisibleSHIELD gives your device a slight "orange peel" finish that breaks up glare and reduces finger print smudges, while still creating high resolution screen viewing clarity.
If you're still wanting the protection of a body skin,but,something that's not as thick/textured,etc...,there's lots of body skin options available:
