I had my Mac overhauled for two days and had to go to an internet cafe to do work. I was shcoked by how good the quality of calls from skype to telephone was from a pc! Why is this? Is Skype actively working on improving the sound quality? And what can I do with a Mac PowerBook G4 that will improve this situation? (Is this situation improved on the new generation Macs?)

Thanks and peace!

Skype is always working to get better quality for video and calls.

Upgrade Skype as the latest version is always the better But pay attention!! Make sure your system meets the minimum requierements (you can check it in the download page!)

Thanks to you for your post.
