One thing that looked really disappointing with Nokia X is how nice the UI looked. Fast lane seems like a nice idea, and I like how it had a notification center. Why doesn't or didn't Windows 8 have those features? Why is Microsoft okay with them releasing what appears to be a more detailed and feature packed forked OS over WP8?
Also one thing I don't understand is their target with these phones. If people buy them like them, and then decide to go for the more "Premium" Lumia line-up what happens when they find out that WP8 doesn't support open source app stores so they can't get a lot of the apps they've been using. Are they just hoping everyone decides to move their apps to WP8 by then?
Overall I'm surprised I think the Nokia X looks like a fantastic phone, the UI looks great and it runs Android Apps which is awesome, I'm just worried that while it will help them gain that low cost market, I don't think it'll increase the higher end WP adoption.
