I take my turn doing youth work and I find they respond quite well to a gadget which can be a bible - they think it's cool; kids today are very easily jaded, so anything that gets their attention is very useful.

So far I've been using my Palm T3 and OliveTree, am trying out rapier on n800 now.

It's amusing that I'm now banned from using "electronic" bible when there's any kind of quiz which involves finding a specific chapter/verse, or searching for specific words!
