Once something like this becomes somewhat popular, even if it's killed by acquisition, there will be clones popping up everywhere. I have Swype on my N9 (once considered state-of-the art input innovation) and I remember anticipating it being on every smartphone. That didn't happen, but now you can find dozens of clones in the Android market.

That's how technology moves. Ground-breaking technology becomes a commodity, often laying the foundation for bigger innovations to take place.
