patrickgeekhack: I currently don't carry around my keyboard too much, but since I am now investing in nice gaming keyboards, I do think that there will be times when I do carry it in order to play LAN parties/events. Also, I take mass transit all the time (I live in NYC), so I can't just carry the keyboard by itself.
