Probably for the normal early reasons, too big, fiddly, and pricey. Someone must have finally shrunk and/or cheapened it enough for a large segment of enthusiast or business for it to gain more attention again.
reading that, it seems to be about consumption/receiving data rather than the sending of data. or do you have light shining out of your laptop back at it?
there is an example of a school using it, and the students have a usb device in their laptop to read the light, but is it slow upload or are they also connected to wi-fi?
For those like me confused about how this would even work.
