My take on pricing
0$ for Nokia Lumia 900 competition = iPhone 4
99$ for Nokia Lumia 820 competition = iPhone 4S
149$ for Nokia Lumia 920 competition = iPhone5 reselling for 199$
I wonder if Nokia will undercut the iPhone5 by having the 920 @ 149$ I think its a smart move great way to gain momentum and build marketshare.
Also note Surface RT I really think its debuting for 199$ if done correctly you can have a killer bundled deal at 199$ which includes a Nokia 820 plus a Surface RT which IMO is a better deal than a iPhone5
