Microsoft was the value of WM. Look at Ericsson, for instance, who thought the word "Windows" would help them. It did not and was skipped.
Windows Mobile has less and less value.
It is as simple as that.

Do you do any research, or just make this stuff up based on half facts?

If you havent heard Acer is an OEM Partner for WM7 ( along with HTC ) so I doubt that they will IGNORE Windows Mobile...

Everyone want to have a go @ WM these days, so know yourselves out ...

Acer makes mobile phones and PDAs? Who the hell owns one and why would you want one next to players such as HTC?

If HTC was to make this announcement I would get worried, but Acer? I say who cares, as long as HTC makes top of the line WM devices there will always be something available for us (by that I mean people who are not stylus challenged). The rest of you can go ahead and buy iPhones, see if I care.
