Google Voice

Google has started its new service "Google Voice", it is currently available by invite only. It is a useful service in my opinion. Now let me describe that how it works. When you register with google voice you will be given a google number, it will be like an ordinary number. Now your friends, family and people who wants to contact you will call on your google number, and you will choose that if someones call you at google number it should ring your home, office, cell number or all of these ring at once and you can answer the phone by any number or any specific number. The best feature of this is that people dont have to remember or store different numbers like home,work,cell etc. Only one google number is enough to reach a person, secondly if you are expecting an important call than it cannot be missed as you can get it on all your phone numbers and you dont have to worry that will he call on your cell or at your home number? isnt it cool :)
