Where have you seen 4 GB cut it in the last decade? 2 GB was enough to make Vista chug in 2007? I've got old linux boxes that feel fine with a couple gig of DDR3, but can't think of a place where that would be acceptable outside of that.
My entire question is why can't whatever users do on computers actually work on 2GB of RAM? Like what is the true reason we are in state that it is for some reason not possible? 2 GB is huge amount information. So surely it should be enough for almost all normal users, but for some reason it is not.
You will find most of your fave programs struggle badly with 2-4GB of RAM, even on Linux.
Over the years most software programs (even on mobile) have become bloated and slow due to "new features" (even if most people don't need them) and also because it is a nexus with the hardware manufacturers. Who will buy any expensive CPU, more RAM, larger capacity SSDs, bigger displays, etc., if there is no software program needing all that extra oomph of performance, bandwidth, and fidelity?
