Don't have any issue with them personally. There is hardly any side bezel.

SIDE RANT:
Even current generation Nexus devices don't get the update right away; they're also on a rolling schedule.
Ummm it is a nexus (er Pixel). It is a developer phone. You sideload it day one straight from googles servers. if you want to wait for the ota push, that is a choice. but the beauty of a non carrier branded, non-locked down phone is that you can make that choice.
