With all the speculation run rampant about the latest and greatest iPods possibly getting announced shortly, I'd like to add my two cents. No matter what shape or size these new 6th Generation iPod Nanos turn out to be, you can rest assured that they will be sleeker and sexier than the PDAs from days gone by. Because screen-protector-technology hasn't realy advanced much, the biggest difference between a screen protector for an 8 year old PDA and a fancy touch screen Apple product is the dimensions of the plastic, and that isn't anything a scissors couldn't solve.
I don't know the whos, the whats, or the why-fors but the screen protectors for the Palm m505 are the dirt cheapest I could find online. Maybe all the m505s are all broken, or maybe Fellowes just manufactured way to many. But for a couple bucks you can get a package of 12 screen protectors. That is dirt cheap. Now it doesn't matter what size or shape the new iPod turns out to be, you can be rest assured that your screen protector will be big enough to cover the iPod Nano Screen, all you have to do is cut it to the proper size. Don't have a scissors? Those are easy to find.
You want to skip all the cheap kiddie scissors and the blunt safety scissors and just get yourself a nice new sharp scissors. Premium Scissors are still crazy affordable and for about a buck you can be assured that the double bevel ground edge on one of these new scissors will cut through a vintage screen protector better than the scissors you've been using to cut apart tin cans in your basement.
