Many of you technology fans may be wondering what the difference between Google Voice and Ribbit Mobile is.  Here is a feature compaison chart the Hankweb team has created!  Feel free to comment on this post about some features we forgot, or something wrong with the table.

* Online calls will be based in the set country, which can save you money, because if you are not in the county you reside in, you will not be charged for long distance calling
** The service will call your mobile phone, and then will call the number you have entered. The person you try to call will see your set caller ID (like your Google / Ribbit number), but you will be using your standard mobile phone
