Taiwanese Tech giant Acer has released four new smartphones at the Mobile World Congress in Barcelona as it re-enters the crowded mobile market after the purchase, last year, of smartphone specialist E-Ten.
The four models target the upper hand of the market under the Tempo brand and are all based on Microsoft's Windows Mobile Professional 6.1; they should in theory be upgradable to Windows 6.5 when the latter becomes available.
The F900 has the largest screen of them all at 3.8-inch and can display a spectacular 800x480 pixels, matching the Toshiba TG01 and the HTC Touch HD smartphone and comparable to the screen resolution found on early Asus EEE laptops.
It has a virtual keyboard and a widget-based home screen. It comes with a camera but no flash. Also onboard is WiFi, GPS and HSDPA compatibility.
The M900 on the other hand adds a sliding QWERTY keyboard, a better camera (5-megapixel vs 3.2-megapixel), a flash and a fingerprint reader to the spec list of the F900.
The X960 can be used as a dedicated GPS device with a dedicated antenna. Surprisingly, it uses a 2.8-inch screen capable of displaying 640x480 pixels. The iPhone in comparison has a 3.5-inch screen and displays 320x480 pixels.
The last model is the DX900 which has the same screen as the X960 and support both 3G and 2G SIMs simultaneously.

Acer has also confirmed that it will be releasing Android-based mobile phones but no Symbian. It is likely that Acer uses the same hardware and simply shove a new operating system, in a way similar to Netbooks for example. All the models will be shipped this year but no dates or pricing have been announced.
