I have run across a couple of interesting articles on the iPhone on slashdot. The first article discusses the pricing of the product and specifically consumers willingness to pay the premium pricing that Apple is suggesting. The short summary is that it is unlikely people will be willing to pay the premium. As a reminder, the iPhone is supposed to be available two configurations: 4 GB of RAM and 8 GB of RAM, and the two versions are expected to be priced at $500 and $600 respectively.
The second article compares the iPhone to the ill fated Apple Newton. Who knows whether it is a valid comparison, but it is certainly an interesting perspective. This author believes that the iPhone will initially sell very well and then demand will dry up rapidly due to the excessively high cost.
