While underway on our special e-book comes news of a prototype of LG with the show as a device that these can operate with a solar panel that can recharge its battery.

With the proper autonomy of electronic books, recharging the battery will be one of our minor concerns, but if such a model came to market, we could probably completely forget it, especially in a country like Spain with so many hours of sunshine.

According to LG, four to five hours in the sun we would use it for a full day. It does not seem a panacea, but since the company promised that during his next year will increase its efficiency by 12 percent and in 2012 will grow by 14 percent. Then it may be a realistic option for recharging the battery.

Competition is presented to the Kindle and this goes hand in hand with Sony, a new electronic book reader that has just been introduced and, as in the case of Amazon’s device, comes with integrated 3G connectivity, so that we may download books wirelessly.

The Sony Reader Daily Edition provides a fairly acceptable screen size, 7 inches, falling somewhere in between that allows good visualization and easy transportation. This size allows even display two pages at once if we use it horizontally.

Two other attractive features make this display: it is tactile and has 16 levels of gray. We, therefore, take notes with the Sony Reader Daily Edition plus more quality viewing of documents, including images or photographs. It comes with a lid and integrated memory to store over a thousand books and a memory card slot.

The content is one of the fateful in many of these devices. At EPUB support and access to public domain books Google Books Library Finder is added, with which we can borrow books from a library.

The metaphor is more than accurate, as well as in a library of physical books, these virtual books exist in a limited quantity, so if all copies of one loan have been caught in someone we expect his return, which is automatically restored after 21 days.

Like the Kindle, currently the Sony Reader Daily Edition is not offered for sale in Europe, although it is based on 3G are more likely to end up coming sooner rather than later, but will require the agreement with mobile operators and publishers and distributors of books. In the United States will be sold beginning in December for $ 400.

Again only in the U.S., Sony has sold its last two e-book readers. These are viewed as Sony PRS-600 and PRS-300, readers who come to popularize this kind of devices with a very tight, although we doubt that the limited functionality is not in a decline, mainly in the basic model .

The Sony PRS-300 model is the first of a new series of readers called Reader Pocket Edition, and its price is $ 199. The other model, the Sony PRS-600 falls within the range Reader Touch Edition and its price will rise to about $ 299 also attractive. Both go on sale this month of August, but again, only in USA.

Reader PRS-300 Pocket Edition has a 5-inch screen and can adquirilo with different colors, another curious and interesting novelty. It is possible to choose between a reader silver, blue or pink. In its 256 MB internal memory can store up to 350 electronic books and the rechargeable battery goes to two weeks. We scaled that Sony does not give us the possibility to extend the internal memory with SD memory cards because you can only enter the e-book content via USB port.

The model with a touchscreen, the Sony PRS-600 has a menu on your screen 6 inches. We may use your fingers, or dip into the touch pen that comes with it. With this accessory can also use your way of taking notes, an idea we like to be present in an e-book reader today. These notes we can export and print when we want.

The book with touch screen that allows it to use memory cards Memory Stick Pro Duo or SD to enhance the capacity of the reader. It also lets us adjust the font size up to five forms and comes in three colors, in this case silver, red and black.

Display quality of both models do not have much doubt, Sony uses them Vizplex electronic ink.
