AT AMAZON, the new Kindle Fire HD. Looks like a big step up from the Kindle Fire. With 4G Internet. There’s also a wi-fi only model for considerably cheaper. The 4G’s service is cheap, though: 250 MB a month for 12 months for a one-time payment of $49.99.

Also, the new e-ink Kindles now have higher-resolution displays, and a backlight.

UPDATE: Reader Charles Epperson emails: “I do not want to nit pick but I thought I should mention to you that the new Kindle is Frontlit not backlit. Frontlighting the e-ink does not tire the eyes like backlight and in this case is very power efficient.”
