eReaders soon to be just another fad

As i was looking through everything that went down at CES 2010, this past weekend it occured to me that eReaders like Amazon's Kindle and Sony's eReader that they will soon be out of date and in the past. I know that when the Amazon Kindle first came out everyone wanted to get there hands on them and that is why they were sold out for days on end. but now that we have a nice piece of technology called iPhone there is really no need to have an eReader when you can just pick up your iPhone and read a book off of that. I know that is might not be the same quality or the same size but it is sure a lot cheaper that buying the Kindle and then having to pay for all of those books or magazines that you may want.
