WiFi in Flight

I briefly encountered the ability to get WiFi wireless on a flight today.  I said no.  This CW article outlines the fact that though this convenience is getting more common, travelers are reluctant to pay.  I find most flights a rare time when I can sit back and think, not connect.  I might use it now and then, on the basis of real need, but not often.  I also negatively react to being nickeled and dimed by the airlines.   They should note that a great deal of their business services can be replaced by increasingly good conferencing systems.  They should be looking to add more quality capabilites, rather than trying to charge for everything.
