Over here everything is high tech. Pointless or not. Of course there are ads on the paper towels. Not real time printed blog content (yet). Missing urinal feature: real time analysis of blood alcohol. Bonus for womens restrooms: instant pregnancy test. Imagine the possibilities: Google could place ads for abortion options and/or pregnancy products on the paper towels. Right now health insurance companies could track your lifestyle a little bit via your credit card trace. Technically they could. Not sure if that is legal, and if they are smart enough to do so. But with personalised mini lab in every toilet you would get an interesting trace of activities. Of course lab technology does not follow the trend of hard drives of other micro electronics and computer related stuff. So this brave new world option will remain scifi for quiet some time. Possibly forever, since we just might run out of cheap energy -that is the basis for all of your lifestyle after all- before high tech might become that sophisticated.
Update:
Like with any sci-fi story there is a google angle popping up minutes after I ramble about it. Coincidency? Of course. Almost everything is. Actually. Get used to it.
