ok, but is it for real?

As real as a three dollar bill!

I can see that it would be great as a portable device, but two things seem like problems. First, it is undoubtedly very expensive, and would be more of a luxury novelty than a real device. It probably has very low processing capabilities too, which means that you couldn’t use it for much other than typing and maybe simple internet or slideshows.

And what happens if you lose one?
