I was visiting YOPY site (I still have my Linux YOPY & although I can't seem to do a damned thing with it I still keep it updated withOS upgrades etc: it is cute & light but useless with no backlight. With YOPY I can't get the damned thing to connect to anything but the sync software. irDA seems to be there - some of my other devices get its id but it fails to transfer anything. So although I have owned it for 4 months I have never connected it to anything but the sync USB.
ANYWAY, while at GMATE (YOPY) site I came across their description of a product called a wearable PDA
This would be COOL if I could believe it existed ..

It says it has a 640 x 480 head mounted display (glasses). I suspect it is a product that has yet to come to market mostly because I don't know any org still in business that supplies PC connectable head mounted display that offers 640 x 480.
