Not to mention navigation - all reviews are mentioning that there is no built-in turn by turn navigation in WP8. Nokia is a clear winner just on that one feature.
I see the 8x is getting good reviews and I also think that the exclusivity deals that Nokia have done will hurt them. Also, the 8x appears to be priced quite competitively which could help it.
Having said all that, I'll be getting an unlocked Lumia 920. It just looks better, has better apps and features and the letterboxing of WP7 apps that is visible in the 8x reviews looks silly.
