My next phone... hmm...

It has to be open (as in "getting root" on the command line).
It also has to offer the same connectivity options as the N900, like Skype, Jabber (Jingle), SIP and all that.

The N8 does not feature neither of these options, no Skype, no Jabber or other IM integration. Switching to such a phone would feel like a massive downgrade for me, although the hardware is very nice.

Told that to a Nokia sales rep when they had a booth with the new N8 on display in a mall recently. Nokia builds great hardware, no doubt. But I don't want to be limited anymore by the OS with missing features!
