Sony Daily Edition PRS-2121

The Sony Daily Edition PRS-2121 is a portable electronic reading device and the first to offer 3G wifi, making it a clear competitor to Amazon's Kindle DX e-Readers. Announced on August 25, 2009 just two weeks after the release of the PRS-600 Touch Edition and the PRS-300 Pocket Edition, the PRS-2121 has some new features not included in those versions.

Of course the 3G wireless capability so it can connect directly with Sony's bookstore for downloading new books, and there is a larger 7" touchscreen with grayscale that has been doubled to a depth of 16 levels. Standard features that have been retained are the e-paper, or 'electronic ink' display which can be viewed in bright sunlight without picture loss, rechargeable internal battery, 512MB of internal memory(380MB accessible) and the ability to view a page in 'landscape mode' which displays the current page horizontally. A new viewing mode is also featured which lets you view two pages at once, just like an actual book. Books may also be imported via Sony Memory Stick Pro DUO or SDHC secure digital card so it is not limited to downloading from the Sony store.
