Begin shipping for an iPad or iPad Mini case and you'll soon learn that the variety of choices is staggering. If you're parachuting, iPad in hand, from 30,000 feet into a swamp, odds are good you'll want a case with military-grade water and shock protection rather than one with chinchilla faux fur and rhinestones. (Or maybe both, who knows?)

There's a tablet case for just about every kind of user imaginable: business travelers who need built-in keyboards, sun-and-surf aficionados, battery-life enthusiasts, even fashionistas.

A year ago we spotlighted the best iPad cases for summer, with a strong focus on waterproof models. This time around we've broadened our roundup to include the best cases for a wide variety of users. And rather than repeat our May 2012 selections, we're showcasing a fresh crop of covers, including some for the über-popular iPad Mini, which began shipping last November.

The abundance of iPad cases helps keep prices competitive. Many are priced at or slightly above the $69 leather edition of the Apple iPad Smart Cover but provide many more features, including water resistance or a built-in keyboard.

This proliferation of iPad peripherals comes at an opportune time: Tablets are starting to take the place of laptops in many work environments, including law enforcement, food service and maintenance. In fact, research firm IDC estimates that tablets will out-ship portable PCs for the first time ever this year. Obviously, this is great news for tablet case makers, who find themselves in a booming market.

A recent J.D. Power and Associates study on U.S. tablet user satisfaction found that 51% of slate owners share their devices with at least one other person. Unlike smartphones, which are highly personal gadgets, tablets are more likely to be shared at home and work, a reality that increases the likelihood of drops, spills and other hardware-damaging incidents.

On the business side of things, 20% of U.S. tablet owners say they use their devices for work as well, the study found. The iPad might not match the versatility of a conventional laptop -- at least not yet -- but its future is bright. It's a great traveling companion, a good choice for note-taking and well-suited to wall mounting, an important consideration in factory settings.
