1. Ditch the goal of moving Symbian to anything beyond dumb phones with cameras
Many people outside of US still use it and want some compatibility with their old phones.
2. Change the name of Meego to ANYTHING ELSE
MeeGo is just the name of the SDK / developer platform. Most consumers will not see that name when they purchase the phone.
3. Release Meego completely OSS and don't hamper people wanting to go in and tinker
4. Start rolling out both (Official stock) Android and Meego on devices and allow for the devices to switch back and forth between the two
You can run MeeGo on N900. I think you can install Android on it too. MeeGo is not ready for any other device yet; not because Nokia doesn't want you to port it, simply because MeeGo doesn't have to features yet to handle any other kind of phone. Nokia doesn't think MeeGo is ready for primetime yet so you will not see it on any other phone for some time.
5. Release a marketing campaign to choose 'the next look of Nokia'
Wait until Q2 2011. I am not allowed to say anything else.
6. Analyze which OS is getting better market traction and phase out the loser
Nokia already said that they are moving to Linux/MeeGo. Qt is the "bridge" to move developers from one to another (just like how Carbon was used to move from MacOS classic to MacOS X). Talking to the people at Nokia, they already consider Symbian to be "legacy" and are already moving to MeeGo.
I hope Nokia will.
