The memory and storage are outstanding. The computer response is very quick, but on rare occasions, it slows down to the point whereby I have to restart it to get it up to speed again.  Since this is a refurbishment unit, first startup goes through three processes to booth up. It isn't a simple operation of pushing the start bottom and it goes right into booting. But even those two minor glitches hasn't altered my appreciation of the product. I think it's a wonderful buy and would buy it again.
