I use the anti-glare screen protectors because they almost eliminate fingerprint smudges. Excuse me but...**** YOU APPLE !!! If I want to put a screen protector on my phone, so be it. WTF? Hell I'm a fanboy and this just irks me. I hope Google's Nexus 1 gets better and kicks the **** out of iPhone sales. SJ is starting to be one helluva Primadonna.
Yes, you sound just like a fanboy. A Google fanboy.
That said, I think this move by Apple is lame. Far too many of their core consumer base at the Apple Stores are the exact same folks who want to feel that their $200/300/400 device is protected the best it can be. A lot of them are first time tech buyers, and they're rightly nervous.
Apple Stores being able to offer them a one-stop shop where they can get any accessories needed to allay their fears has always been a huge plus. Hard to see how any "durability" impression upside will outweigh this benefit, or beat the simple human need to protect expensive baubles.
