I use a Kindle. Not very often, but sometimes I put some code in a .pdf on the Kindle when I'm trying to work through somebody else's code. Light bedtime reading. <grin> At bedtime, there's no deadline pressure to stop you working through small points carefully. And then there's the subconscious factor, where your brain will keep working gently on your problem overnight. And allow you to have a 'sudden insight' at some later time.
