Soribook is a South Korean eReader, but unlikely to be easily available outside the country. It is a fairly recent version of the Taiwanese Netronix EB-600, the most copied eReader design in the world (a pity it isn't particularly exceptional). It has the same basic hardware as the the European Cybook Gen 3, the UK COOL-ER and Elonex, the Russian Pocketbook 301, the South Korean NUUT, the Polish eClicto, and the US eSlick and Astak Mentor Lite. It uses e-Ink display technology for low glare, high contrast viewing, just like the rest of the latest generation of eReaders.
The minimalist design is in black plastic, with only a joystick-like keypad and four other buttons to control it.
It comes with an impressive 1 GB of memory, enough for over 2,000 books. However, if this is not enough, then you can add more memory via the SD card slot.
The lithium ion battery is the biggest we've seen, and should last some 10,000 page turns--or nearly 3 weeks of heavy reading. And other plus is we do note that it changes pages quickly, faster than the Sony PRS-505, but not the improved Kindle 2. It charges via a computer on a mini-USB 2.0 cord.
Connecting: The Soribook does not have wireless capabilities of any sort, and must be synched via USB cord to a computer to download content. It also has among the poorest file format support (10 formats) of the current eReaders. At least for these formats, it does support them natively, with no conversion. However, even supported formats like large PDF documents can be a pain to read--displaying too small to be readable and difficult to navigate.
Accessories: A black leather cover is available.
Price: Unknown--not easily available outside South Korea.
