While it's a great idea, the Moshi isn't worth it. I bought it from the local AT&T store for about $30 and applied it in a couple seconds. I got home and realized that I put it on *slightly* off, so I took it off and washed it, then left it to air-dry. I let it dry for a bit more than 48 hours, and then I picked it up to apply it to my A2. There was STILL bits of residue from the water that was easily visible. I washed it again and dried it 3 more times, getting as much water off the screen as I could, but 2 days later there was still signs of water.
So, unless you can find a place to put a piece of plastic for a week without any dust getting on it, don't even think about washing it. As for the notification LED, I didn't notice it because it was only applied for a few hours, but it's certainly a deal-breaker for me. However, I'm a bit skeptical about Moshi's excuse. How could they NOT know that there was a notification LED for such a device? It sounds to me like the just didn't see it 0_O
Sigh... off to the AT&T store for me to see if I can get a refund, although I threw away that cheap (but expensive!) piece of plastic a couple days ago :\. It's too bad about the notification LED, because otherwise I would be willing to buy that again and just not wash it
