Keep snoops from watching your iPod
A protective screen shields the display
As this item comes from our cousins across the pond, we're tempted to make a snide remark about prim-and-proper Brits--but then they'd retaliate, and we'd lose. So we'll just note blandly that Crave UK has found an privacy screen (pronounced with a short "i") from iStyles for the iPod, which shields the display against prying eyes while riding the tube or in other congested venues.
Japanese subway riders have had a similar product for awhile now, but it makes sense that the idea would arise in their country first. After all, no one knows overcrowded transportation like they do.
