Having to wait and sometimes pray for your vendor to ship an update is why I chose to stick to the Nexus line of phones until it ended.

My next device may or may not be a Pixel, but the above coupled with the shitty "value adds" like custom file managers and stuff that Samsung et al tend to cram into their already bloated Android implementations pretty much guarantees I'll never by a Samsung or similar.

My wife's Galaxy S3 was slow the day she got it, and it only went downhill from there, to the point that a spare BB Priv felt like an upgrade to her. At that point the Priv was already 2 years old.

edit: can someone explain the down votes? for real, I thought this was a pretty level headed comment. is it just that I dumped on Samsung?
