I have the Story, and about half of the eBooks are tech books. (You are aware of O'Reilly's "EBook deal of the day" $9.99 eBooks? Look at oreilly.com)
I am very satisfied so far, the firmware updates released since I have the device (1.61) have very much improved the usefulness, enabling zooming on pdfs and reflow. The keyboard is nice for searching, but I use this rather seldom so far.
What should be improved is enabling pdf zoom in landscape mode and enabling access to bookmarks from within the book (you have to got to the home screen for that).
I have tried the Story in a bookstore (after ordering online
) while bringing a SD card with a variety of books. The firmware in the store was old, so I would recommend to bring the current firmware with you on the card for an update
