IMHO what Nokia could do is to let Skype know the unhappiness of IT users. Say "Skype, you see we are bundling as agreed, but users are upset at the quality of the bundled software"

Second point, I agree that momentum is great, it's the problem of the chicken and egg. I would use google talk and gizmo but at the moment I have 5 contacts which use gtalk and around 50 on yahoo messenger. I would give up the resource hungry yahoo client (I'm talking about the winxp one) in no time but I can't.

The same for voice. I would like to use gizmo or gtalk, but I am tied up to yahoo and skype (yahoo being no voice both on my IT and on my Symbian phone)
