I was hoping no one would call me on that part either. But I'm going to claim ignorance of how those really work. > In any case, a computer requires neither a display, nor a keyboard.

Ambient, IR, whatever. The flashlight thing is too cumbersome, I want a full-size QWERTY keyboard. OK, tactile feedback will not exist, but otherwise... This is the one I was thinking of: http://www.virtual-laser-keyboard.com/ The first generations would be just a chunk of plastic you sit on the desk and it does the display and keyboard. Later generations would be even more "wearable" once the holographic I/O devices are sorted out. Assuming the neural interfaces don't beat them to the punch. Either way, we end up here: http://www.dilbert.com/fast/1994-10-12/ http://www.dilbert.com/fast/1993-03-10/ http://slashdot.org/article.pl?sid=01/11/14/1828253 > Of course, this only qualifies as a computer with no moving macroscopic > parts.

Look, as long as we don't actually LOOK for them, who's to know? :-) JP ----------------------------|:::======|------------------------------- JP Vossen, CISSP |:::======| http://bashcookbook.com/ My Account, My Opinions |=========| http://www.jpsdomain.org/ ----------------------------|=========|------------------------------- "Microsoft Tax" = the additional hardware & yearly fees for the add-on software required to protect Windows from its own poorly designed and implemented self, while the overhead incidentally flattens Moore's Law. ___________________________________________________________________________ Philadelphia Linux Users Group -- http://www.phillylinux.org Announcements - http://lists.phillylinux.org/mailman/listinfo/plug-announce General Discussion -- http://lists.phillylinux.org/mailman/listinfo/plug
