I'm over the fact that the Pixel 3 models will only have 4GB, but the above poster is right, it's absurd to assume that going with 4GB of RAM means the money saved automatically makes other areas improve due to re-allocated resources. You don't know this. Nobody knows except Google, how resources are allocated. I'm confident Google could have found some way to fund an additional 2GB of RAM without sacrificing quality elsewhere. Why so little faith in a multi-billion dollar company? Isn't RAM affordable these days? You're saying Samsung can do it, but Google can't?
It's also silly to keep bringing up the iPhone with 3GB of RAM. So what? That's a different OS. Isn't Android multi-tasking much better than iOS' anyway? Doesn't it make sense to compare something closer, like another Android device? And why compare down? Why not compare up, say like MKBHD does with the OnePlus 6? Why are we setting the bar to "good enough?"
Heck, let's just discuss the Pixel 2 XL -- MKBHD and others have already said the RAM affects real world usage. Why do we keep ignoring this when they're telling us point blank?
And as I said before, if limited RAM means I have to wait for apps to reload, then that is slower. If I can use an app right away versus seeing a big white screen and then waiting for the content to reload before I can use it, that is slower. You can argue that the wait to reload is tiny or that you yourself don't use so many apps that you often see reloads, but none of that changes the fact that it is slower.
The Pixel 3 models will have 4GB of RAM. We all have to come to terms with that and then make our own decisions with our own wallets, but some of the arguments and excuses made here for Google are unfortunate. Google doesn't need your defense. What Google needs to do is compete better, plain and simple.
