as what i have read from the Q&A with elop at MWC, is that, nokia may be depending on microsoft and pay them royalties for it, but at the same time, there will be no more money spent on OS development. so those factors just balances the situation. ( and it may be cheaper just to pay royalties too )

he also stressed out that microsoft is actually investing money more than nokia coz of nokia's location based services & etc. ( as elop has claimed, by the billions in monetary worth )

i believe even if nokia has prioritiezed meego lesser or even the least now, that even though doing so means wasting a lot of money and effort invested already, it would still be the wiser choice in penetrating the US market. since meego is not really as welcomed there compared to WP7. also, as i have seen with intel's prototypes in MWC (video), meego still has a long way to go in terms of development as compared to an already polished, and currently already selling WP7 OS.

so did nokia really ruin themselves? not really. coz even if they dominate the rest of the world, it would still be something else for "total" world market domination again, as they used to.
