Making PC-to-PC calls wirelessly

In a few days, I will be able to make Windows Live Messenger (formerly MSN Messenger) voice calls anywhere at home. You may wonder what's so good about this one compared to other Skype wireless headsets. The unique advantage of this phone is that many people are already using Windows Live Messenger and have lots of friends added to their contact lists. The user does not need to switch over to another application and to set up another account to do PC-to-PC voice calls and instant messaging. They can simply get the headset and start making calls. In case you are wondering, you can also make "land-line" phone calls with this headset. I am aware that as a first generation product, it may suffer from many bugs. But I am also thrilled about the possibility it brings to my daily life.
