We already have skilled people successfully getting a modern kernel on it. MeeGo, is - probably much to everyone's joy, consistent with many of the "ambitious Mer" goals and also backed by substantial resources and is a platform a lot of different device vendors, communities, etc will use. This work on the platform would be directly transferable to our N8x0 devices.
Convince me otherwise. I DARE you. Don't tell me how awesome everything WILL be. Give me some tangible evidence that Nokia or TI or ANYBODY involved gives a care about the N8x0 series or that they aren't already doing the same dances around the N900 now.
