Keyboards haven't yet outlived their usefulness, and Logitech continues to make some of the best for adding a little something extra to your iPad.
Here we've got a quick look at the Logitech Keys-To-Go. It's a ridiculously thin keyboard for tablets. The one we have here is technically marketed for Android and Windows — it's got a telltale Windows key as well — but it'll work with iOS, too. (If you just have to have one sans Windows key, there's a more iOS-friendly one available, too.)
There are a couple ways to use this keyboard. The sexier of the two is to already have the tablet propped up somehow (perhaps with Logitech's own propper-upper), and then have the keyboard away from the display in a more comfortable manner. We'll call that "future mode." But given the resolution of tablets these days, you might want it closer. So there's a removable plastic clip that lets you stand the tablet up in the usual position right behind the keyboard.
