So the one you treat well will last longer. The same make of CPUs inside, the same hard disks and so on make any guess at longevity a guess. While I get 4 years out of a laptop they are never dropped, sat on, loaned out, etc.
I have been looking for a laptop for a while now and narrowed my choice to Dell E1505 and a HP DV6000t
I bought a 1505 because it had better warranty (at home service), lower price for same features what is the mood out there do people like dell E1505 or the HPDV6000 t
Let me know your choice based on the following criteria
* Reliability and Durability (Which will last longer)
* Price (Get more with lower price or at lower price)
* Build Quality
