There are a lot of people out there who would really appreciate a Kindle. Of course Kindles are overpriced since a digital copy of a book isn't even worth a cent, yet they charge you something ridiculous like $10 for one.
The wife and I have a gift rule. Limit of $1! She gets me pizza spice at the Dollar store. I get her a thing of bath powder at the same store.
For her birthday a few years ago I got her four art books from the mid 40's, they were marked 15 cents each. I paid $1200, but lied like a dog about it.
