Is all the required software onboard the device itself? I thought it was using some kind of paired application to handle processing the input.

>With the TextBlade, WayTools can deliver over-the-air updates to keep firmware up to date, something that's not possible with most keyboards. The TextBlade will have more functions six months after it's released than it does today. For example, one upcoming update will add multi-device support, and that update is coming a few weeks after launch.
The keyboard can't get OTA updates unless it can communicate with the update server. That means it has either WiFi or 3G or the tablet gets the files and uploads them to the keyboard. Probably the latter.
It's not rocket science, how hard can it be to make a bug-free keyboard firmware? It's not this is virgin ground either, keyboards have been built for decades which had no bugs.
Well, since it uses multitouch and some smarts to figure out which letter in one of the merged keys you wanted to type, I imagine it would be more useful to update that algorithm than in a keyboard where one button press = one keycode. This goes especially so if that algorithm uses any text based prediction, although I don't know whether it does. The multitouch, combined with an accelerometer I read the device has, could also be used to add interesting gestures or pressure-sensitive functionality that don't directly map to key presses. You could send the raw data over the air instead of using firmware on the device, but then nothing would be able to use it out of the box, so what's the advantage?
I think you're being purposefully obtuse here. This device is obviously more complicated than a standard keyboard and would definitely benefit from having a) sophisticated firmware, and b) the ability to update the firmware.

So it seems that there is enough brain inside the device to handle it all, if I'm reading that correctly. Interesting.
