The Apple iPad has many strengths, but its on-screen keyboard isn't one of them. It's a problem with tablets in general, especially if you're more interested in getting actual work done than sending birds flying through space. For productivity, an external keyboard for your tablet is a must-have. You could opt for a standard add-on Bluetooth keyboard, like Apple's own $79 Wireless Keyboard, or, even better, get a combination case/stand/keyboard to protect your tablet in transport, and prop it up for video watching.

Keyboard folio cases come in a variety of form factors, ranging from thin and flexible to sturdy and substantial, but the main draw is the good old-fashioned hardware keys. External keyboards not only bring that familiar tactile feel to your tablet, but also free up valuable screen real estate so you can see and do more while typing. These keyboards also include some convenient iPad-specific function keys like Cut, Copy, and Paste, as well as Home and Search keys.

Knowing that many of you haven't yet upgraded to the iPad Air or Mini, we've also included some keyboard cases to fit your older iPad. Some of them are advertised for specific iPad models, such as the iPad 2, third-generation iPad, or fourth-generation iPad, but those three older tablets are all very close in size and will fit each other's cases. If you have an iPad Air or iPad mini, just make sure the case you're checking out is made for the right model, as they won't fit in cases made for previous-generation tablets.
