This video from a 15 year old UK student demonstrates a successful installation of gOS on a laptop nearing a decade of service.
He installed some snark in his YouTube video notes as well, noting that:
I managed to install gOS on a 9 year old IBM ThinkPad 600E laptop. This video shows just how well Linux will run on pretty much any hardware. Vista doesn’t look much better than gOS and would never even boot on old hardware like this, let alone run demanding applications such as GIMP.
