Amazon's Kindle Paperwhite drops to $120 for Black Friday

Ereaders like the Kindle Paperwhite make great gifts -- especially when they're on sale. The Paperwhite adds a few perks over the standard Kindle, including a warm backlight, a waterproof build and a larger screen. As part of Amazon's Black Friday sale, it's now $20 off the list price, bringing it down to $120. This is the 8GB model with lockscreen ads, which usually promote Kindle books. Other Amazon ereaders are also on sale, including the standard Kindle, which is down to $80. That's $15 more...
