With the new UMA (Unlicensed Wireless Access) phones (Nokia 6136, Motorola A910) the move to wireless VoIP is inevitable. If you have a mobile phone that can switch seamlessly to Wi-fi when available, the game is over. You only need GSM or CDMA service as a backup option when there's no Wi-Fi and for call forwarding so people can reach you. All other things you can do over Wi-Fi connection. You just have to have VoIP client sitting in your mobile phone.
If you already have free Wi-Fi in the office and at home, public Wi-Fi network around the city, that's all you need 90% of the time.
As for Microsoft entrance it is good news, but nothing that important. There are a lot of good VoIP services that can readily be ported to Pocket PC, Symbian or Java and run on any mobile phone. If you can do it with Office great. But the same can be said for Skype, Gtalk and others.
