I don’t have an iPhone, but I have used one in the past. I never liked how the touchscreen keyboard has no haptic feedback, and so I don’t “feel” if I’ve hit the right key. This is why I like the Blackberry Storm.
For those of you who are fans of BlackBerry’s keyboard might like the iTwinge. Simply put, it is a handy slide-on keyboard for your iPhone so you can “feel” the keys. The company states that it can improve typing speed by 30 to 40 percent, and reduce errors by 70 to 80 percent. Not bad, but it costs about $30.
