On Wednesday, Casio casually announced the release of their 2011 EX-word denshijisho collection the XD-B Series, a mere 10 days before the release date of the first models. Let's take a look at what's new!
First of all, they've updated the design, which is the first major design update in several years. Looking at this "business model" the XD-B8500 as an example, they've nixed the angular edges of the previous models and replaced them with smoother rounded lines, giving a more book-like appearance. Additionally, some models will sport a new texturized shell.

Taking a look a the keyboard, you'll immediately notice the addition of a full color sub-panel, which is a smaller version of the main Blanview display. With the backlighting, you'll be able to study in the dark! This new display also gives more advanced viewing options; full text or thumbnail images for example, providing a more integrated user experience. One minor negative of the sub-display is the minor loss in overall battery life, an estimated 20 hours compared to the XD-A series. Flanking the new sub-panel are two circular controllers. The left side houses the internal speaker and feature buttons such as history, while the right side has all important the navigation arrows. If you remember, I wasn't happy about the squishy feel of the navigation buttons on my XD-A9800 model so I'll be excited to see if they've remedied this part.

Much to my relief, there isn't much that has changed internally. As far as I can tell, the main and content dictionaries are the same, aside from an Oct. 2010 update to Kangorin, 8th Ed. of the Oxford Advanced Learner's Dictionary, and 5th Ed. of the Longman Dictionary of Contemporary English. Aside from Kangorin, these are not dictionaries I use regularly. The one feature that I am interested in testing is the search, which is supposedly "smoother" than before. And the inclusion of multiple keyword and image search is interesting, but I'm not sure if they only apply to the encyclopedia data.
The new Casio EX-word XD-B models will be released from January 21st and into February, and beNippon will have them ready for order as soon as humanly possible. So save that left over Christmas or otoshidama cash!!
