PS on for good
I've had a PS antiglare protector on since May (when I got my iPad). Love love love it. Makes the iPad usable in many situations where I don't want a mirror. I suppose there is some kind of clarity tradeoff, but I'm not discriminating enough to care. (I don't regret giving up vinyl records for CDs either.) As an added bonus, the screen is protected from scratches etc. so I can scruff it up and still protect my investment.
I can't stand glossy, except on my iphone where the screen is small enough that the mirror effect isn't distracting. My MBP is matte and my ACD is matte, and I'll be using these until they fall apart if Apple doesn't offer matte versions of them. 😛
P.S. I'm now using the Camera Connection Kit to download my DSLR pics, and it's working excellently. No discernible degradation of image. Of course I will use my laptop for editing and photo tweaking. But for display purposes, the iPad is marvelous.
