I've just been doing some informal polling with readers in my area (all of whom are women except for DH) and they were taken aback at the cost. I then asked if it had a calendar and address book whether it would be worthwhile and they all immediately said that they would buy it. Hence my question. Like Bk said, if you have to lug it around why not eliminate some other things we have to lug around.
More features gives the Reader value. At this point, everyone I have asked said they like it but it is too expensive to do one thing. Despite my arguments that ereaders actually save money, I am not making much headway.
