eBook readers are like any other technical device - by the time you paid for it and walk out of the store they are old technology. That doesn't make them old or tired. And if we wait for the latest model, no one would ever buy one as there are always rumours of a new improved model.
I would buy a reader for someone even if they haven't thought about buying one yet. Here in Oz there are still many people who don't know much about them and are surprised when I show them my Sony.
I would have to consider the person though: are they avid readers? Are they comfortable around computers? Are the books they are reading available for them here in Oz.
