I generally agree. My only doubt is for the sales prospects for Meego devices (phones + tablets).
WP7 showed how difficult it is for another major mobile OS to take hold. Meego asks for consumers to think about yet another.
Also, for devices coming at the tail end of 2011, Nokia doesn't really have any kind of scaled up tablet ecosystem, aside from Ovi Maps or Messaging, that'll translate to larger finger-touch friendly devices, or any type of content store. If they're planning on announcing partnerships and media deals, they're cutting it awfully close.
(It's also why I see Samsung's announced Galaxy player, that's going to compete with the iPod Touch, to have few sales. It's essentially a Touch without content or a PC software music and video sync client. They should ask iRiver, Cowon and Creative how that strategy worked out for them).
