The Acer comes with Window 7 already installed. The HP you have to upgrade.
I had to search wide to get reviews and details since that beyond the processor (a Pentium Dual Core T4300), you did not specify models.
The clear winner here is the "new" Acer not the "Refurbished" HP, in fact the Acer would have won against a new HP of this type.
It wins because of Windows 7, because it is new with a better warranty and because of many other smaller details.
