Can't believe so many of you like kindles - I love the weight of a book, the size of the text, the quality of the paper the pages are made from, its smell, hardback or paperback - it all adds to the pleasure, you can't get that with a kindle. Call me old fashioned..
Still think you should go with the camera - there are great things you can do with photoshop etc to prolong the fun - he could have his own website, my brother teaches guitar and lute and has recently turned to photography producing fantastic images, great fun and a good parallel to music (the language is the same - composition, value, balance etc).
