Today we don't have much control over the laptop
configuration. We have to choose a portable from one of the list of available
models from the manufacturer (it is true that big manufacturers provide a
myriad of models to try to accommodate all kinds of user). Even with
manufacturers that allow personalized configurations, you have to order the
laptop and they will assemble one with the exact specs you requested and have
to wait the system to be delivered. Today there is no way to build your laptop
like the way we build desktops. @ Hardware Secrets
