BBM 2.0 gives you spotty notifications at least on my Nexus 5 using ART. I switched back to Davlik and i got notifications back. Blackberry needs to fix that.
Re: Would you still buy a Moto X post Motorola/Lenovo Deal?
Yup. Getting my son one for his birthday. It just got KitKat on Rogers. Thats all he will care about. That and he can play all the latest games. Who cares about next year. If it comes down to it i will root it.
