not just a pen...

[SensoVision]

Everyone have probably heard, seen or even used pens which are remember all moves during handwriting and later transfer all data to PC for later use as images or recognition with OCR software.
But now I've read about another product which not only perform actions described above but also able to interact with person while writing, e.g. it could translate words from English to Spanish, it check orthography or used as calculator(you just simply draw buttons on the paper and later click on them). And it could be used as usual pen of course
It's all sounds pretty cool IMHO, wonder how it works in reality.
Here is official site of this pen:

That site is too annoying for words... I found an interesting video on YouTube about the Fly Pentop, it's worth looking at. It works only with Fly paper, presenting a challenge to cost effectivity. I know when I'm in school I tend to use lots of paper (I'll go through several journals in a semester), and I'm certain it's even more excessive in middle school.
