Anything at that level in Windows world is decidedly entry level -- suitable for office tasks, but not much else.  And anything a $500 PC notebook can do, so too can a $250 chromebook -- or said another way, a $500 chromebook will have features such as a tablet screen that a $500 Windows notebook will not.   You can get a decent desktop system for that -- notebook, not so much.
Is there any dell laptop with good speed and memory under $500?
