Those of you who have been thinking about getting an ereader may want to check your local Borders or WaldenBooks store. They are having a sale while supplies last for the Sony 505 Ereader priced at $199 with a $10 off coupon for an ebook. In stores only, they ran out of stock online. That's the cheapest I've ever seen it.
For those of you who are still looking for cheaper means, did you know you can download an app on your iPod Touch or iPhone? Check out the assorted apps here: ipod.about.com
I've heard very good things about the Stanza app.
If you have another smartphone, you can also (usually) download ebook software.
