The X-Ray tool lets readers tap a character name, place or topic in the text and bring up a list of all the places in the book where it is featured.
If the book you're reading has the X-Ray feature, it will display when you tap the top of the screen to bring up the menu when reading. Both the books we read during our test period had the X-Ray feature. It seems Amazon is quickly expanding the range of books available with X-Ray, as when we reviewed the Kindle Touch model back in May we were unable to find any books that had it enabled.
You can access information on locations as well as characters, with a list of every mention of them in the text, so this could be a useful tool for students preparing for essays or exams.
We tried out the 3G model of the Kindle Paperwhite, and were impressed with the speed of downloads. We chose a book, hit Buy and it was available for us to read in seconds. However, we don't really see the need for a 3G model over the WiFi option, especially when you're looking at an extra £60. We can't imagine there'll be many times when a reader is stuck with no access to WiFi as it's so widely available across the globe now. But if you're a business traveller visiting lots of remote regions and wanting to be able to download your daily newspaper, or the type of person who'd be terrified of being stuck on a train or the beach having finished all their current books, then the 3G option is for you.
According to Amazon, the Kindle Paperwhite lasts for eight weeks, based on half an hour of reading per day with wireless off and the light setting at 10. We found that using the Kindle over sustained periods with the light turned up much brighter drains the battery much quicker, although we still managed to use the Kindle Paperwhite on and off over the few weeks we've had it without needing to recharge from the original 100 percent.
The Paperwhite offers 2GB of internal storage and can hold up to 1,100 books. This is less generous on-board storage from Amazon than the previous Kindle Touch model, which offered storage for up to 3,000 books via the available 3GB. However, anyone concerned that 1,100 books just isn't enough for their insatiable reading thirst, you can rest easy: Amazon offers free cloud storage for all Amazon content, so you can delete books from the device and then reload them from the cloud when needed again.
