You misconstrued what I was referring to by my use of "they." The antecedent was the videos, not the person who made them.
It sounds like for you, 2GB is sufficient but lots of people use lots of tabs, from my observations. People also often keep tabs open because they are reading at a specific place on a page.
My work involves lots of web applications, video editing, extensive Javascript debugging and flipping between many tabs. Without working OpenGL, this would be bad enough. With 2GB, it becomes much less possible.
The way most web developers are going, in a few years' I suspect almost everyone will hate having 2GB.
ARM binaries are smaller but that doesn't matter if you're required to use a lot of bloated web sites.
