Speaking as a chronic eczema sufferer (for over twenty years), with my hands particularly affected at times, I have to state that a blower dryer gives me far less grief and I go for this option when I have the choice. Furthermore the environmental impact is not that simple to assess: you need to factor in such things as the cost of making the paper, shipment to site, laundering the towels, employing someone to re-fill the dispenser, etc. etc. But I agree that it's hard to convince others.
