There's a storm brewing on the horizon. One that may change the Windows Mobile community in more than one way. Acer is slated to introduce four new Windows Mobile phones to the U.S. market.  Acer's Tempo Series includes the M900, the F900, the X960, and the DX900. Information Week is reporting that when these new phones hit the shelves sometime in late April, cost will be the main marketing tool. While no U.S. wireless provider has spoken up to partner with Acer, the company hopes to offer these phones at a substantially lower cost or possibly free with a service contract. had the opportunity to interview Acer's Smartphone Unit President Aymar de Lencquesaing last month at Mobile World Congress. The Acer executive said he'll be able to push Windows phone prices down to free with contract. "We'll make it a very simple, easy interface ... and these will retail at zero dollars," de Lencquesaing said. If this develops, it will be interesting to see what affect "free" smartphones will have on other manufacturers. Especially if the Acer's are quality devices.

The potential for free smartphones is just one aspect of this invasion. Launching an application store might be another aspect of Acer's leap into the Windows Mobile market. During a recent London press event, de Lencquesaing said Acer is examining the viability of an app store, which would be accessible from its new range of Windows Mobile phones. With Samsung and Nokia having similar App Store plans, this isn't that far of a reach.

De Lencquesaing has commented that he wants Acer to be in the top five of smartphones within five years.  If Acer can match low cost with quality phone, they may have a chance to reach that goal.
