The amount of people who use Skype is currently growing with 4 million new users in 12 days. That's almost as much as the entire population of Singapore. Almost a third of all registered subscribers now use Skype for their businesses.
Phoning someone is now disconnecting itself from the device. Later on we’ll be able to phone from any device (TV, computer, mobile phone, mediaplayer, PSP, e-paper, whatever) using, for instance, Skype. The model of telecom operators will be decimated to offering (very good) connectivity of all those devices.
