I use the Skype Android app on my phone. Here in Canada you can use 3G connectivity to make calls with it (you can't in the US apparently) though at home or places where I have Wi-Fi access, I use that.
I don't know what's with all this talk that Facebook voice chat can replace Skype. No it can't. You can call actual phone numbers with Skype (though obviously this costs money).
Since MS is going to continue to allow non-Microsoft platforms (like Android, iPhone, Playstation Portable, etc.) I don't see what the problem is. Microsoft would be idiots if they made it exclusive to Microsoft platforms. I wouldn't give up my Droid for a WM7 phone just to use Skype on the go.
