I am a long time fan of skype. It really does have something to offer the user.
1- Widespread international adoption
2- Cross platform interoperability
3- Ability to call landline and cell phones directly
I use skype occasionally to make phone calls from my Touch over wifi. No need for a cell phone plan!
The video for Skype on my Mac is pretty good, certainly good enough for a video chat. They have saved us thousands of dollars over the last several years. Or, more accurately, allowed us to keep in touch with friends and family overseas in a way we never would have without them.
Skype is definitely one of the good guys!!!
Obviously you haven't spent any time on the Skype forums. Skype is one of the most unsecured platofrms out. It is riddled with scams, holes, and the Mac vesion of Skype is a resource hog.
1. Yes it is internationally adopted because it was first. Truphone could be a real competitior if they could get their act together and they are.
2. As for cross-platform, the Mac version is simply aweful.
3. Truphone, Fring, and a few others offer the same thing.
Maybe you have low standards but Skype is aweful. Hopefully FaceTime will put pressure on Skype and they will fold.
