I have read this whole thread and have yet to find ONE example of where Maemo 5 is not supported. PR 1.3 was just recently rolled out and there have been no indications yet as to whether or not PR 1.4 will come. And no, not getting the latest version of maps, flash etc does not count as "no support". Neither does not providing source for the various closed source bits (as much as it does suck). So yes, you can say Maemo 5 has been deprioritized by Nokia and treated like a bastard son. But saying it is unsupported is an outright lie.
