I'm getting frustrated waiting too, but it's hard to imagine a company as big as B&N making a mistake on something this important. eReader is a legacy product. B&N doesn't need to have "tech savvy" to understand what that means; surely they've been around long enough to understand.
There are rumors of at least two new ebook readers with eReader support being released before the holidays. On B&N's own WEB site one of their most used threads is a pleading from many customers for eReader support for Linux. There seems to be a critical mass building up.
One would think that nobody needs to remind B&N that selling books is what they do. Copying Amazon, a department store that sells all sorts of products, is a snipe hunt for B&N. In a future where ebooks are increasingly how books are published, getting as many readers needing books in the hands of as many customers needing content as possible has to be the key to profit in B&N's market.
In the meantime my own wishlist at B&N keeps growing while I wait for content I can read on a real screen. And in the meantime innovators like ShortCovers, which sells ePub editions with their own iPod app so I can read their product on my iPod, Sony or PPro, are taking market share that B&N may not be able to get back. The longer B&N delays the more serious challenges like that to their real core business there will be. They have to realize this as well as we can. On the other hand, Keynes's "animal spirits" seem to rule the business world at the moment.
