Well, the little iPhone Kindle app has convinced me that a Kindle2 might not be a total waste of money. I'm actually enjoying read both academic and non-academic books on the iPhone. Although the Kindle2 doesn't have a backlight, it looks like it'd be a good way to read before bed or on the airplane.
I wish the Kindle2 had WiFi, I guess that -- along with the backlight -- is my big concern for the unit. Especially as Sprint might be going bankrupt if it continues to bleed customers like it is now. I wonder what will happen to the Kindle's EVDO if that happens....
I'd love to hear from anyone who has one.
