In an earlier article, I wrote about several cases that make it easier to get a good grip on your iPad. This article builds on that one and includes additional cases that let you wear your iPad on your shoulder or neck. A comparison chart is included for your convenience.
At CES and MacWorld, I wanted to hang mine around my neck like an electronic sandwich board! Several vendors have stepped up to the plate with various approaches. DIGIPOWER, modulR, and OtterBox offer ways to add a strap to your iPad so you can carry it like a shoulder bag, or in my case as a sandwich board.
The DIGIPOWER solution is called the Coffee Clutch. It is a case, with a built-in stand as well as a built-in handle. They include a neoprene strap that can be attached if desired so you have a very versatile device. I liked the comfort level of the strap, especially since I wore it around my neck all day! And when you get where you're going, the built-in fold-out stand is nice to have.
modulRcase.com offers a system where a shoulder strap is just one option of many. You get a rubberized case with four nubs on the back. You can attach a hand strap, a shoulder strap, a desk mount, a wall mount or even a fridge mount using those nubs!
I liked the DIGIPOWER Coffee Clutch's neckstrap better than the modulR one, as the neoprene is more comfortable, but the modulR folks tell me they may have a better solution soon. Also, carrying around a separate handstrap and deskstand could be a pain. The hard rubber modulR case feels better in the hands than the Coffee Clutch's hard plastic, but the clutch's built-in handle is really nice to have.
The OtterBox Latch is new and offers a host of features. The OtterBox Latch works with or without the case of your choice, by attaching to the corners of the iPad. There are straps and an S-biner clip to attach an included bag for cables and chargers. OtterBox includes straps for your hand, thigh or neck. You can even use the straps to mount your iPad on your car's headrest.
