The Next-Gen Skype
After seeing what the Google Hangouts could do to Skype, I really think there is a need for Microsoft to up it's game with the Skype offerings.
A better Interface, though the present one is not bad, I think there should be a overhaul with a very modern design that appeals to users.
Make the LOGO more metro and more marketing as a messaging solution with VOIP, Video and IM is very necessary.
Skype is mostly used for video and audio calls, but the messenger part is almost unused, I see some potential there for improvents
Skype is still not integrated into outlook.com in my region, I m not sure about others, and this has to be done soon.
Skype should be a default app present in Windows 8 and on Windows Phone.
The desktop app (not the metro one) is really bad if you ask me.
