There are several different versions of the Kindle Paperwhite. The one tested was the ad-supported WiFi model, which costs $119 (£109). For slightly higher cost, you can get one that does not have ads. And how are these, by the way? Are they super intrusive and completely annoying, like most advertisements? Actually, they were not nearly as bad as we feared.
On the Paperwhite's home screen, you'll see a very small add at the very bottom of the screen. It's hardly noticeable. And when the device is not in use, a full page add will appear, almost like a screensaver.
When turning on the Paperwhite, which is done by hitting the power button, you can either do a swipe motion to unlock the device, or hit the Learn More button to purchase what is being offered. Even in this state, the ads are pretty innocuous.
There are two other versions of the hardware. The WiFi plus 3G model for $179 (£169), which again is ad supported, and the WiFi plus 3G, sans ads for just a little more. Unless you are downloading a new book literally every five minutes and absolutely cannot stomach ads in any form or fashion, the most expensive version seems a bit excessive. For those willing to spend more for such a configuration, it is available.
