I put the Skinomi tech skin on my Nexus 7. I am less concerned with scratches than I am with glare and fingerprints. It works great for that purpose and protection is just a side benefit. It is a little more expensive than the cheaper products, but the quality is worth the cost. It uses a wet install method that is much easier to do correctly and since it is air permeable, any bubbles will disappear after a few days. It's also a soft rubbery material that is resistant to abrasion. There is a very slight amount of drag to it, but if you learn to glide your finger with slight pressure it is barely noticeable. Bottom line - if you want less glare and fewer smudges then give it a shot. If you go with the cheap stick on protectors, you will probably be disappointed. This is based on my experience with the brand and not on any connection to the manufacturer.
