The iPad makes a great poolside or beach companion, provided you don't mind a little screen glare. But sand and surf can wreak havoc on your delicate silicon slate, hence a heavy-duty case is essential for frequent outdoor use. The LifeProof nüüd case and cover/stand ($130) keeps a full-size iPad dry even when submerged under 6.6 feet (two meters) of water, the company claims. It safeguards your slate from drops of up to four feet (1.2 meters), and it meets the stringent IP-68 requirements for protection against dirt and snow too. So what doesn't it have? There is no screen protector, but those often reduce screen clarity and degrade touch input anyway.
