Nope. Microsoft had a few manufacturers on board. That's all. Some independently played with mobile Linux, but those have mostly been supplanted by the Android consortium.
ROFL!
Going by your list,
“China Mobile
Broadcom
Qualcomm
Synaptics
TI
LG
Motorola
HTC
Samsung
Vodafone (Verizon)
Sony Ericsson
Toshiba
ARM
Marvell
nVidia “
every single one of them firms had Windows Mobile or some form of mobile Linux on smartphones going in one way or the other.
Again, I ask ya, if simply having these firms on board is all that it took, how come the other versions of Mobile Linux and Windows Mobile couldn't take the world by storm like Android has?
