Phone design isn't my cup of tea

Yeah Kevlar is great and would be lovely to have but make it look better!
Hardware looks great (assuming UK gets S4 chipset) and huge batteries is great, should get some epic battery life when combined with the S4 and SAMOLED screen

of course assuming that the software is also optimized well enough
Hopefully the camera will be as good as the X/S and GS 3, usually this is one of the biggest downsides for Motorola phones.
And the software looks nice, hopefully with google backing them up, it means that they will now become the best for software skin and updates.
Dual core is OK for now, but for future software updates and based on a 24 month contract, I wouldn't want a dual core phone if I can help it on an android phone.
WP8, not such an issue, but having gone from a S3 to the original dual core atrix, Im noticing the massive speed decrease..
As said, the S4 chipset is in a league of its own when compared to every other dual core CPU and it is far better than the quad in the X and better than the exynos quad in the GS 3 when it comes to sheer performance per core, battery efficiency and heat. Plus the majority of android apps still don't fully utilise dual core let alone quad.
If there are 2 nexus devices coming in November, both exactly the same specs, but one has the S4 chipset and the other using the same exynos quad chip as the GS 3, I know which one I would be choosing in a heartbeat
