If you use an iPad poolside or on a beach, consider the waterproof Lifeproof nüüd (HK$1,240). Adding 310g in weight, the nüüd allows an iPad to be dropped from over a metre and survives being in two metres of water for up to 30 minutes. The nüüd creates a watertight seal around the bezel, leaving the iPad's screen completely naked - hence the name.
The Griffin Survivor (HK$625) gives protection for the iPad 2 and iPad 3 with a shock-absorbing silicone-covered polycarbonate shell. It can be dropped and used in extreme temperatures. It's perfect for skiing (most gadgets tend to shut down as the mercury hits freezing), but it'd be ideal on a building site, too. Hinged plugs can be pegged back to reveal the camera lens, volume controls, dock connector and headphone slot; when closed they're completely watertight.
The Drogo, (HK$780) in black leather with a gold suede interior, pays homage to the dragon in the detailed embossing on the front. Its Safe Guard Bumper tech soaks up shock waves if dropped, though a hand-loop on the rear makes the Drogo easy to grip. We liked the business card/document holder inside and the smart magnet technology that activates the "sleep" and "awake" functions on the iPad when opened and closed.
