While E-TEN may not be as big a name in the market of Windows Mobile-powered smartphones as say HTC, I have to tip my hat off to the Taiwanese company for their latest handset. Designed to be an update to the “popular” M600 handheld, the M600+ (yes, the plus means more, except the minus of an integrated GPS) offers a few upgrades over its predecessor, while maintaining most of the things that made the original what it was: a simple design with a whole lot of connectivity.

In addition to standard quad-band GSM/GPRS, the E-TEN M600+ features built-in Wi-Fi connectivity and Bluetooth 2.0 (the M600 only had v1.2). They’ve doubled up the included memory to 256MB, and the camera is now a 2.0 megapixel shooter. As far as the OS, the E-TEN M600+ comes preloaded with the latest version of Windows Mobile 5.0. What this means is that you’ll be able to take advantage of Push Email, an area that has traditionally been dominated by Research in Motion and their BlackBerry line.

The E-TEN M600+ is expected to “be available soon in all regions,” with a price tag just a smidget above the now-dated M600.
