I think the problems with both readers is a symptom of the respective companies loosing focus on their target markets. These specific products are trying to satisfy too many industries at once. Instead of trying to address publishers, distribution, and customers all at once; these companies should have focused on doing one thing and doing it well. A simple book reader that just handled pdf files and was priced competitively to books (less than $100), would stand on it's own. However, being priced at >$400 means that these products have to solve many problems at once (availability, distribution, and hardware), and if they don't do all three well, then they will fail.
