There must be a demand for waterproof cases. Not long after we mentioned to you about the DryCASE, the folks at Benzitech sent us info on their new iDry waterproof cases for smart phones and tablets. The cases seal a device to keep out water, yet allow the devices’ touch screens to be used through the case without removal. They can submerge down to 30 feet underwater, and they float, too. The iDry products come with waterproof ear bud headphones, armbands, and neck straps.
