Gizmodo is reporting that the new Sony ebook reader will be coming to market in October priced at approximately $300.
While I'm sure this not going to be the final form factor for ebook devices, this Sony device is good enough to make some applications feasible. For example, certain textbooks would do well on these readers. If a book already costs $100 plus, having a $300 reader for a bunch of textbooks could make economic sense and it would greatly reduce the weight students would have to haul around. I'm waiting to see textbook publishers start to include update options so that the textbook can be updated over time.
Another nice feature with the device is that it accepts RSS feeds and standard file formats. This make an entire world of content available that the first generation ebook readers restricted. This is a very wise decision on Sony's part. The market killed the first generation devices -- apparently Sony learned from this experience.
