It's a close call either way. Another issue is that both have reports of overheating when people run them 24x7 or when gaming. These are not desktop replacements so you'll want a laptop cooling pad to attempt 24 hour operation.
Nothing stands out on either. A friend has the HP unit and there is nothing to report except they feel like it's slow. But that's Vista for you and it would do same on almost any machine.
Im between these two laptops but cannot decide. Can anyone offer any input? Here is a CNET comparison chart. THANKS http://shopper.cnet.com/4504-6496_9-0.html?tag=pageNav&id=32976281&id=32909853
