Acer's smartphone quartet

Acer has chosen this year’s Mobile World Congress in Barcelona to officially re-enter the smartphone world with no less than four models in a range it is calling its Tempo Smartphone series.

The four are the direct result of last year’s buy-out of smartphone specialist E-TEN.

You can find news and pictures here.

The four models are:

ACER M900 With a fingerprint reader for advanced data security the M900 runs Windows Mobile 6.1 Professional and supports HSDPA. It has a sliding keyboard and a 3.8-inch, WVGA touchscreen.

ACER F900 Also sporting a 3.8-inch WVGA touch screen the F900 has built in GPS and again supports HSDPA.

ACER X960 This time with a 2.8 inch 640 x 480 pixel screen the X960 again includes a GPS antenna and supports HSDPA.

ACER DX900 Perhaps the cream of the crop for business users the DX900 supports two SIMs. With a 2.8 inch 640 x 480 it isn’t quite as multimedia friendly as the M900 and F900, though.

All four devices have a widget based interface sitting on top of Windows Mobile 6.1 Professional. There is no word on whether they will be user upgradeable to the newly announced Windows Mobile 6.5.
