This keyboard may look and even feel fragile, but the fact is that it performs very, very well even when given an unexpected drop test. I had my TextBlade in my breast pocket as I jogged across a street. I had just made it to the other side when I heard a clatter of plastic on the sidewalk, and turned in horror to find that my TextBlade had taken a tumble and hit the ground hard; the QAZ and OL. keys both popped off, and the spaceblade was partly unhinged. I grabbed the parts, checked them for damage or debris, cleaned off a bit of dust that had gotten under the butterflies, snapped the keys back in, and it's like nothing happened. Not bad for a device this tiny and complex taking a spill from five feet up onto rough concrete!
I've had other folding keyboards where falling out of my lap from a chair was enough to irreparably damage them--they still worked, mostly, but the hinge in the middle was never the same again. TextBlade is different--no mechanical hinges to break, for one thing, and for another important factor, the keyblades can flex and keys can pop off to absorb some of the impact energy, without the keys or mechanisms being too badly damaged in the process. (Even so, I'm not going to make a habit of knocking this thing around!)
I'm glad that I had a TextBlade in my pocket, rather than a less durable keyboard. I'm also profoundly glad that my TextBlade didn't fall in the middle of the street--it may be durable, but I don't think it could have handled getting run over by a car or a bus.
Testing continues, hopefully with fewer drop tests.
