E-TEN M550

The upcoming M550 is targeted at mobile users who are looking for a cellular-enabled Windows Mobile 5.0 device yet don’t won’t to pay for extra options like integrated Wi-Fi or GPS. It is essentially an older M500 model with the latest OS pre-installed and some visual tuning.
The novelty is powered by Windows Mobile 5.0 software for Pocket PC Phone Edition and supports quad-band 850/900/1800/1900 MHz GSM/GPRS Class B cellular connectivity. Under the cowl it has a 400 MHz Samsung S3C 2440 processor with 128 MB RAM and 64 MB ROM (130 MB total available to the user).
The handset features a 2.8-inch full color QVGA (240 x 320) screen, SDIO expansion slot, built-in Bluetooth, and a 1.3-megapixel camera with flash (up to 1280 x 960 resolution). I am a bit disappointed because M550 still maintain its 1.3 megapixel camera.
The M550 measures 111.7 x 60.7 x 22 mm and weighs 170 g. The standard 1440 mAh Li-Ion replaceable battery allows up to 4 hours of talk time or up to 200 hours of standby.
