I noticed the new Kindle that comes out in May has a special price right now that includes some great free offers and an amazon gift card. Plus it's on sale for $114 ($25 off the regular price).
I have the 3G version (which isn't on sale right now), but if you don't mind only being able to access the web for new books when you're near WiFi, then this is a fabulous deal!
Wondering what's the difference between the 3G and the WiFi version? With WiFi, you can get books whenever you're near a wireless internet source, or when you are plugged into your computer. With the 3G version, you can download books from almost anywhere. It uses technology similar to what a cell phone uses to access the internet and you can download new books while riding in the car, on the beach, or sitting in an airport. If you're content to load up your Kindle with books before you hit the road, then you'll be perfectly content with the $114 model.
NOTE from 4/17: I figured out why this one is a better price and includes bonuses. The screen savers will include some advertising that is catered to your interests. It says it will not interfere with normal reading.
