Great new! Skype released official Skype version for Android. The application works great, support almost all the features of the desktop Skype. Most importantly, you can make Skype Calls.
Try it your self, to see how awesome it is. I found some little bugs, but I guess that they ware in a hurry to release it and I bet they will update those. Also it can’t send files, but who cares if everything else works. 
PS: I plan to be Online 24/7 from now on.
