Re: Suggestions for an ultra-mobile device for eBooks? What does a bit more functionality mean? You need to make sure that his desire for ultra portability isn't in conflict with his expectations. For example is he looking at e-readers but really wanting an ipad?
Much depends on his preference in book store.
I have a sony pocket reader but there is no audio and I read primarily works that are out of copyright in open formats, so that wouldn't meet his needs.
If he has no preference in store then I would think the latest $140 kindle would be tough to beat. I haven't used one but it seems to reset the bar in value for money. If it had been available when I bought my pocket reader I probably would have gone with the kindle. I just didn't feel the $3-400 they wanted for the kindle, at the time, was warranted for my needs.
NOTE the $140 version has wifi but NOT 3G. To get that you need the $190 model.
