What do you want to do with it?
For most vendors, there is a big difference between their consumer hardware, sold based on price, bells & whistles; and their corporate hardware, sold based on cost of ownership - availability, manageability, serviceability, support. In many cases, the corporate model is worth the extra cost up front - it saves much more in headaches down the road. But usually they lack features for gaming and some other consumer or specialized applications.
I've seen many HP corporate models last seemingly forever - so long that the users grow frustrated because they can't justify a new computer. There's a ~14 year old one not far from where I'm sitting that runs perfectly and is in perfect condition, other than the pointstick (it has a trackpad too).
