Who's really killed who?

Often when new technologies emerge, people are quick to call out the 'death' of the existing older technology.
Recent ones I can remember is Google+ killing Facebook and Twitter, or Google Wave rightfully ending email's woeful existence. Heck, even SMTP and DNS are still alive and kicking!

However, thinking about those perhaps leads us to a more relevant question: Has Mxit suffered from other technologies like BBM, Facebook, Twitter, WhatsApp, etc?
I wonder what Mxit's active userbase is now?

And from Silicon Valley this morning:
Reports of the PC's demise are greatly exaggerated, according to Intel CEO Paul Otellini, who said Wednesday that the Santa Clara chipmaker had record sales of $13 billion in its most recent quarter.
