Clever techy t-shirt

I love the thought behind this T-shirt that has a microfiber strip built into it for cleaning your glasses, your iPhone, or whatever other gadget you have handy that has fingerprints and smudges on it!  I'm not sure how it would fare with the regular washing cycle, but thumbs up for the clever design!  However, at $89, I certainly wouldn't buy it.
