Is the Kindle Paperwhite worth it for someone who only reads at night?

Yes — for someone who only reads at night, the Kindle Paperwhite is usually worth it if you read regularly and want the most comfortable Kindle screen for dark-room reading. Expect to pay about $140–$190 new for the current Paperwhite, or about $90–$150 used/refurbished depending on condition and model.

The main reason to choose it over the basic Kindle is the warm front light and smoother reading experience in bed. If you only read occasionally, the basic Kindle can be enough; if you read most nights, the Paperwhite is the better buy. As always, prices change, so check sold/completed listings before buying.
