How is 4GB RAM installed a niche use case? If this is the route software development is intended to take where every app is going to consume +4GB RAM good luck running multiple apps at the same time or running it on a smaller form factor. It is truly bizarre that we are moving away from the desktop PC to smaller form factor but at the same time pushing technology that requires a desktop PC.
