The Nokia 3610 Fold is an interesting handset just announced that features dual screens. The clamshell design features ergonomics that Nokia is calling “understated elegance.” Outside you’ll find a 1.3 megapixel camera with 6x digital zoom, along with the external display.

Inside you’ve got a 2-inch, 262K color screen and the Nokia phone softkeys. It also supports up to 4GB microSD cards. It gets released officially in the third quarter of this year at $186. While I wouldn’t call it sexy, it does have a certain charm. It’s aimed squarely at those who just want basic features without a bunch of bells and whistles.

The iPhone may have some competition if this dual screen display concept is ever realized. It’s called the Plica phone and it’s like the Nintendo DS of phones. One of the screens is a touch screen keyboard, the other functions as a touch monitor. You can also view an entire web page on a single display or have them spread out across both.

Designer James Piatt’s idea was no doubt inspired by the DS Lite and has a ton of potential. It’s one concept that has a decent chance of seeing the light of day. I’d say that if Nintendo were going to build a phone, it would be something very similar to this rather then a Wii phone.

Much like Kenny Rogers, the Xentex laptop knows when to fold em. It knows when to walk away and when to run. It wasn’t satisfied with simply opening and closing. Oh no. It can fold twice for portability. That means that the system has two 13.3″ screens that can independently swivel so you can share your stuff with your friends sitting opposite you.

Together, the screens combine to measure 19.5″ across for a huge display. Inside it’s got an 850MHz Athlon processor and 128MB of memory. It’s kind of like having a Rubik’s computer. It can be found on ebay and as of this writing it’s at $405.00 with 11 bids, 6 days to go.

With the success of the XO laptop from OLPC, it makes sense to start working on a second generation device called the XO 2.0. It will be much smaller compared to the first one, and will feature a foldable e-book factor.

It will also be just half the original’s size, with dual indoor-and-sunlight displays that provide both a right and left page when held vertically, a hinged laptop in horizontal format as well as a flat, dual screen continuous interface for tablet mode. Power suckage has been reduced to just an impressive 1 watt. You’ll have a nice long wait though, since it will be released sometime in 2010.
