The K3 Keyboard and the Voyage are the best Kindles IMHO. And I even had the same neon-yellow/green origami case for mine. Gave the K3 to my MIL when I upgraded to the Voyage. And sold the Voyage when I wanted to free myself from that walled garden a few years ago.

If you don’t want to get rid of your Voyage, you can turn it into a TRMNL and have it show your calendar, news, etc. instead.
