Engadget noticed the Sony Reader at Best Buy, but it didn't seem to have many takers. Their post asks readers how they'd change it: " ... should they have loaded it up with more flash, or at least made it compatible with memory cards bigger than 4GB? Would out-of-the-box support for Mac and Linux users help? How about a non-crippled RSS reader?"
Lot of interesting comments, so be sure to read those, too.
