Take a look at the weekly sales at
Office Depot. A couple weeks ago, I bought an impressive Lenovo G550 for $400 + $40 tax. They appear to have two different laptops on sale each week. Their weekly sales flier available online often has a sneakpeak for next weeks sales.
My experience is also that HP makes crappy computers that often break. But again, I may see more broken HP laptops than from other brands because more HP laptops are sold than other brands. Therefore, more people own HP laptops.
I do not recommend an HP laptop.
=============================
Here is my personal preference order:
Asus > Lenovo = Apple > Sony > MSI > Panasonic = Toshiba >>
Dell = Gateway = Acer > eMachines >>
HP > Compaq
I am unfamiliar with Samsung laptops but expect high quality on the level of Sony.
=============================
When shopping for a laptop, I look first at the following:
screen resolution: 1366x768, 1600x900, or 1920x1080
Memory: 4GB
Processor: AMD > Intel
The rest is marketing fluff. The size of the hard drive does not matter since files can be safely stored on an external drive cheaply.
