Looks like Acer’s going to be putting more of its mobile eggs in the Android basket next year, with about half of its handsets in 2010 to feature Android instead of Windows Mobile.
"Acer, while still developing Windows Mobile-based smartphones, has shifted its development policy to focus more on the Android platform, with at least half of new models launched in 2010 to be Android-based, according to industry sources."
The Android-based Acer A1 should be making its official appearance in the coming months, with the WinMo-based F1, L1, C1, and E1 becoming available by the end of the year.
