Amazon announced three new Kindles back in September: the fourth generation Kindle, the Kindle Touch (and Kindle Touch 3G, both of which are identical aside from the 3G antenna), and the Kindle Fire. The Kindle 4 was available on the same day, and we've already taken a good look at it. Our Kindle Fire review is forthcoming. That leaves the Kindle Touch, which we're going to talk about today.
The Kindle Touch is Amazon's first touchscreen e-reader - past Kindles have used nothing but buttons for navigation, even as competing products like Barnes & Noble's Nook Simple Touch began to incorporate touchscreens. At $99 and $149 for the wi-fi and 3G versions ($139 and $189 for the ad-free Kindles), the Kindle Touch is priced competitively, but how does the touchscreen actually impact your reading experience?
Before we get started: Many things we covered in our review of the non-touch Kindle (hereafter referred to as the Kindle 4, to avoid confusion), including screen quality, page refreshes, supported file formats, software updates, and general usage, are still applicable here. If you haven’t read it yet, you should look at our Kindle 4 review before continuing.
The Kindle Touch’s box is nearly identical to the Kindle 4's: an unadorned cardboard box containing just the Kindle, a micro USB cable, and a small cardboard insert with basic directions for powering on and charging the device. The manual proper, which has more detailed directions for using the Kindle’s touch controls and other features, is stored on the Kindle itself, and will be launched automatically at first startup.

The first thing you notice when comparing the Kindle Touch to the Kindle 4 is the lack of buttons, of which the Kindle Touch has just two: the Home button situated on the front of the device, which looks vaguely like a speaker grill, and the power/sleep button located on the bottom of the Kindle next to the charge light and headphone jack. Two speaker grills on the back provide basic stereo sound.

Unlike the 3G connectivity of Kindles past, the Kindle Touch 3G’s connection won’t give you free and unfettered access to the Internet. Here, it’s used solely for WhisperSync, for browsing the Kindle Store, downloading purchases, or for looking at Wikipedia - no other sites are available without a wi-fi connection. This move is probably a good business decision on Amazon’s part (and, given the uneven nature of the Kindle’s still-experimental web browser, probably not a terribly disruptive one), but if web surfing is something you do with your current Kindle 3G, prepare to make some adjustments before upgrading to this model.
The Kindle Touch uses version 5.0 of the Kindle software (compared to 4.0 in the non-touch Kindle) - the layout and operation are mostly the same, but the implementation of the touch keyboard and controls and the new X-ray feature were apparently enough to merit the bump in numbering.
