If you do not like to upgrade things I'd go for the samsung, I just did some research and it seems samsungs have good reviews and low failure rates. I was a technician for a year and never seen a samsung come through, although that could be because of them not being so popular.
That being said both laptops have their draw backs.
Pro's for the HP: Faster processor, e-sata ports (something that MAY be more useful in the future), windows 7 professional, backlit keyboard
Cons for hp: integrated graphics which means you'll be sharing your ram with graphics processing, not too bad if you dont ever play games, shorter battery life
Pro's for the Samsung: Dedicated graphics card, longer estimated battery life with the lithium polymer battery
Cons for Samsung: Windows home premium (still not bad), Lower line slower processor but it may still be quicker due to it having its own graphics processor
All in all its really what you plan to use it for, I think either of the laptops would be a great investment.
