The kindle by Amazon looks pretty cool, but I can't figure out if it will be a niche market for a long time, or whether this is the breakthru product that will make ebooks really take off. I don't think it will be for commuters, but maybe for people who are on the road a lot of the time. I can see avid readers who don't like killing trees or storing used books to buy into this big time as well. But I just don't know if that's a big enough market to make it really take off. What do you think?
