Currently using Google Talk when at home to make calls from my laptop when I'm at home to save valuable air time on my Tracfone. On the plus side, the calls I place are free and I can talk as long as I'd like. Downside is that it looks like the number that shows up on people's Caller ID varies and that the more I use it, it seems a bit glitchy.
I've actually tried to sign up for Google Voice, but my carrier isn't recognized. My thinking is that since I don't want to be tied to a new mobile contract, I'd have to research and buy a prepaid/no contract/pay as you go from a supported carrier.
However, my wife has Skype. She's only used the IM feature so far- she was a mod for a UK based Pokemon themed game site, and that's how the staff communicated. I realize quite a few of you here are happy Skype users.
Since Microsoft acquired Skype, I was wondering if y'all have noticed any change in the quality of service/product. Any ideas of whether Skype will continue to be a stand alone app or do you feel it's destined to be soley an IE plug-in and only available to people who use IE?
