You're saying the manufacturers are lazy, but with this and the Nexus phones that come without added stuff, you can set them up however you want with different launchers and keyboards. It seems like perhaps it's you that doesn't want to go to the effort of finding the apps & settings that make it just how you like it. I personally prefer the manufacturer NOT make those decisions for me, as it leads to a lot of bloatware that takes up space, computing power, and delays & complicates updates. To each their own.
Also, the Google Keyboard is getting better about providing a number row at times when it might be useful. It would be nice if they'd give the option to have it always there, though. I love the Google keyboard overall, and there's no reason I'm aware of not to provide that as an option.
