Make your PSP waterproof with Aquatalk
While Aquatalk looks like a slightly upgraded ziplock baggy, it's supposed to keep your PSP waterproof. It should do so because it's covered in four layers of protective coating and has a secure anti-leak zipper seal. At 740 yen a bag (roughly seven dollars and a chunk of change), it better deliver. The bag is good for both fat and slim PSPs.
It's a pretty cool concept being able to get some gaming done while making one's self clean in the bath. We might actually give this one a try ... well, only if someone wants to lend us their PSP for an experiment. One warning though, we probably wouldn't recommend this for scuba diving; you wouldn't want to get distracted playing Loco Roco when a shark comes to bite your head off.
