Remember when people used to say that the iPhone was useless for e-mail as it doesn't have a hardware keyboard? Think back: it was a while ago, around the same time that the iPhone was doomed for not supporting Flash.
Got it? Well, apparently some people somewhere still think that way, and this post is for them (if you know one of them, perhaps you could print out this article and fax it to them or something). Yes, you can now turn your state-of-the-art iPhone 5 into an also-ran BlackBerry.
The Keyboard Buddy clings to the back of the iPhone 5 like Yoda to Luke in The Empire Strikes Back, only instead of badgering you about trying and trying not, a keyboard out of it slides.
And if you're prepared to thicken up the thinnest iPhone yet, you'll be presently surprised. The keyboard sports five rows, all of them backlit. What's more, it'll last two weeks per charge, and you can keep using all of the iPhone's hardware features (camera, buttons… screen) without removing it.
I tend to think that a tiny hardware keyboard is no better than a tiny on-screen keyboard, which is why I am writing this on an iPad paired with a full-size Apple Bluetooth number. But that's just me. For your luddite friends, this might be just the thing, and it's only $99.
