What's the difference between the Kindle Paperwhite and the Paperwhite Signature Edition?

Per pcmag.com and Best Buy's product listings, the Signature Edition adds an auto-adjusting (ambient) front light, 32GB of storage versus 16GB, and Qi wireless charging, while sharing the same 7-inch display and processor as the standard Paperwhite. Reddit's r/kindle community is split on whether those perks justify the premium; many say the standard Paperwhite is the better value unless you specifically want wireless charging or auto-brightness.
