It is good to travel light yes. I once insisted that we take The Complete Letters of Oscar Wilde on a day trip (three times heavier than his complete works) and it didn't go down too well, but the potential of the kindle can help solve things like that and more.
I rejected the idea of an ereader for a year or two, but really it was silly. It is just dated nostalgia, most of it I think.
(Damn, no wonder I am a little tired I have just realised it is 2.08am! - all the best, good night.)
