Seriously, anyone who claims mobile phones are the work of the devil, and should not be trusted, but will then use someone else's whenever its convenient, is a hypocrite not a visionary.
Sorry, my initial comment was about RMS and 'freedom in computing'. The article(s) are more about his ability to lead a team, and in that they may indeed be valid (and at first glance do seem to be). As to the cellular phones, sure they have been empowering to almost everyone in the world (and I esp. think of 3rd world countries), but I think we have yet to see the end game. Hypocrite, maybe, practical yes.
What if one likes the potentials of mobile technology but doesn't like the tracking mechanisms that may be involved in it?
...or getting you on the same list of subversives he is on.
