The originating group of developers are actually rather brilliant and came up with one of the fastest p2p communication protocols. Once the closed-source version of Skype opened up, it went a tad downhill with every kid releasing their own client. I don't recall specifically whether or not the n810 client is put out by Skype themselves or not. All I know is the official Skype client runs like a champ on most desktops/laptops without issue.
