"This isn't a decision we've taken lightly, but the reason is simple. Neither of these apps offered a great Skype experience." SO what is a great Skype experience? I find this decision strange for an application that has been in the mainstream so long. When software are outdated, you are usually offered an upgrade that fixes the bugs. They are not removed.
Imagine what life would be if Microsoft, Google, Apple and others just pulled out there software because THEY think the user experience is not good enough. If that was regular and accepted business practice, I guess we'd be running our gadgets without software. We'd be carrying bricks around pretending to make a call over IP; pretending to be enjoying a fabulous user experience on our phones that Microsoft and Apple developed and then pulled out.
Clearly this is a decision taken lightly. So long Skype.
