Update: I installed my techskin yesterday, and it looks fantastic. The screen looks even more glossy, less prone to finger prints. Still waiting on a few tiny bubbles to disappear on the back. The one thing that I love, and hope not to jinx, is the fact that it will not turn yellow (as advertised). I put it side by side with a 3GS who had an invisible shield on for the past couple of weeks, and you could tell there was a huge difference in color immediately (IS was already quite yellow).
I also liked the overall feel of the techskin better (screen glides pretty smoothly), and while it still has somewhat of an orange peel effect, it's definitely not as bad as the invisible shield. I'll take a picture of it once the bubbles go away in order to give everyone an idea of it.
Since the techskin isn't a popular item that is talked about frequently on forums (couldn't find anything when searching for related topics), I'll also continue to give updates as to the status of my techskin, for those who are curious about buying one, or even researching alternatives. So far so good *crosses fingers*
