all in all pretty much agree w/ your post except for above statement;
i think you are not quite fair w/ the electronic industry @ large.
keep in mind that NOKIA is in the position they are / were (dominating the mobile phone market) a little bit like IBM was 30 yrs ago in the PC market. of course, they had outstanding products (both HW & SW wise).otherwise they wouldn't have gotten and stayed in the dominant position.

specifically, a few yrs ago i got a SAMSUNG 780i from the company i was working @. the HW was outstanding but the sw... well, it was m$, right?
other companies can and will continue to provide HW that runs the m$ software;
especially if the Intel CPUs (under what form ever) become available & it becomes WIntel all over again.
in which case it might be possible to install MeeGo (or any port thereof) just like it is possible to install Linux / GNU on practically any PC which comes w/ LostDOS preinstalled...
which brings us back to the next Maemo / MeeGo device ¦-)

that this is all NOKIA was hopping for when they decided to bind Maemo's fate to Moblin would make sense, provided that wp7 got off the ground (which, a year & 1/2 ago seemed possible).
as this last thing did not come true (yet), it was either waiting for a miracle to happen or step in.

it may still require a small miracle for wp to become the dominant OS in the mobile phone market, but the odds have improved, haven't they?
