Well personally I hate it.
But it does make sound financial reason for US market where Nokia is a laggard..
In US Nokia is a distant 5th, mainly because they (yankees)think symbian is not good enough for high end phones.. As the ASP of phones is quite high in US compared to countries like India , Nokia want to get foothold in that market IMHO.
Most of Nokia's success has always revolved around India,Russia,China and a few countries in Europe.
But now with the new "Look west " policy,I am afraid the midrangers will get trashed. They will churn out high end phones for the US, and keep their registers in developing in countries like ours with phones like 1100 series...
After the continous android onslaught for the past 2 years in these areas, I had expected Nokia to do something like this,But surely not take it as primary OS. They could have continued with symbian as the main OS with Maemo(or meego) and WP7 as side arms. But unfortunately they dont share the same views as mine or other countless fanboys.
I can still say N8 does make a better phone then any other, emphasis being on the "phone" part, But the condition of market is such that people expect to get a pc bundled with their smartphones,and for that function the fruits and desserts are much ahead I am afraid.
