If things go to plan I think we will see a MeeGo device this year.
Problem is, with M$ clanking around in the engine room, will they stick a spanner in the works and demand a crippled release to scuttle the Good Ship MeeGo in favor of pushing people onto WP7 devices. Remember, M$ hates open source and Qt and would want (read as "be desperate") to get WP7 to market in quantity, and they're not gonna do that if MeeGo turns out to be the killer O/S we're all hoping for.

When it does arrive, I'll certainly give it a good look. I've already got an upgrade path sorted, so I'm gonna be in possession of an N900 and the new MeeGo device when it happens. Should be an awesome combination, IMO.
