Although NEC previously announced o­ne of these phones, this is the first time I've seen the other two.
The first time I saw the picture of the N910, I thought "hey that looks like a Gameboy Advance SP."

NEC announced that they will introduce three phones aimed at the Chinese cellular market. These are the pendant-shaped "N910," the ultra-thin digital camera type "N900," and the flip-phone type "N820" that also has a QVGA screen.

N910



The uniquely designed pendant-shape N910 is a phone targeted at women. The back side of the screen can act as a mirror, and it includes a .3MP camera. The phone also supports capturing movies up to 15 seconds long in the Motion JPEG format, and also supports 64 channel ringers. The size is 52 x 57 x 21.2mm (W x H x D), and the weight is 76g.

N900



The flagship model "N900" was announced back in February. It's an ultra-thin digital camera size GSM/GPRS phone, with a .3MP camera. It uses a 128 x 160 dot TFT color LCD. The size is 85 x 54 x 8.6mm (W x D x T), and it weighs 70g.

N820



The "N820" is a folding type phone that has a 2.2 inch LCD display with QVGA (240 x 320 dot) resolution. It includes support for 3D displaying Java applications, as well as a .3MP camera.

NEC is looking to establish a presence in the rapidly expanding Chinese cellular phone market, with the forthcoming standardization of 2.5G or 3G technologies in the country. For this reason, to plan and research products with the cooperation of China, Japan, and other countries, they have established the "Chinese Mobile Terminal Project Advancement Headquarters." They will push the NEC brand, and work o­n developing patents and new phones. NEC plans o­n introducing 20 products into the Chinese market in 2004.
