Acer, the world’s third largest PC maker, is getting serious about cellular phone market. Today, Acer announced 4 new Tempo-series smart phones for the Asia-Pacific region, showing its ambition in cell phone maker, after seeing the recent boom of smartphone / PDA phone market. The 4 new smartphones are X960, F900, M900, and DX900.

X960

The X960 looks very alike to HTC Touch phones. In fact, the phone has almost identical features of HTC Touch, such as GPS, PDA, camera, MP3 player and a widget-based friendly interface for instant access to the web, email and your life online.

F900

The F900 is there to challenge iPhone 3G. It features a gigantic 3.8-inch WVGA touch screen. Like iPhone 3G, the X900 phone relies on visual QWERTY keyboard for input. It features a widget-based home screen based on Windows Mobile OS.

M900

The M900 looks very alike to Pantech Duo. The phone is powered by Windows Mobile 6.1, and is designed for mobile professionals who need to access corporate emails frequently. The phone has a gigantic 3.8-inch WVGA touchscreen, a sliding QWERTY keyboard, and Outlook Mobile.

DX900

The DX900 is the world’s first dual-sim phone to support 3G and 2G Sims. This feature allows users to have flexible mobile connectivity for fast Internet access on the same phone. This might not make sense for US users whose phones are mostly carrier locked, but for other countries, where users are free to swap carrier by having changing sim cards, the dual-sim feature would help users.
