GTalk works as fine as Skype. The only difference is that the protocol is open.

Talking about "obsolete" - I'm afraid it's Skype we'll have to say good-bye to in a few years... in my job I see all these VoIP-Solutions emerging, all with a high market potential. Of course, they all are built upon SIP rather than Skype.

So forget Skype for the N800; what we need is SIP-integration in the IM-user interface...
