I am disappointed that the Linux users still do not have the same basic functionalities in their software as the Windows users have. As Linux is expanding its user base, would it not be a good idea to try and keep those users that have helped Skype become as big as it is and offer them these basic services.
I have read several other users' opinions in the other forums but see that Skype is not keeping up with the trend towards Linux. This is surely loosing you users as they search for other softwares that can give them the capabilities of a very good software you have already crerated (i.e. the Windows version). Their friends and families will also be encouraged to use other softwares as will some corporate users, giving the smaller companies a chance to really compete. It's your politics, but I always believed that once you have satisfied customers, questions should be asked if you start to loose them.
Without at least the video capability (although others say call forwarding, other PC speaker etc.) it does put the Linux software in a different ball park from its Windows equivalent.
Just food for thought.
