We have 3 Dells and 1 HP. I wish I knew more about them, but 2 of the Dell's I hate. They are way too heavy. The screen is bigger, which is nice, but I think my back would break if I had to carry it around. My Dell is smaller, but if very powerful. It was also the most expensive (it is for work, and it needed to do certain things.) The HP was a cheapy, I think $600 or less a few years ago. It has been fine, but even though it is a laptop, it stays put.
It really depends what you want the computer to do. The HP is
DH's for work, my Dell is for work as well. He mostly needs the internet and MS office, not much else. Since I am in IT, mine needs all kinds of firewalls, programs, etc. The other Dell's Dh got for a steal. They were from a university that is under contract to update every year. So they are only a year old and sturdy. We use one for pictures and the other is pretty much for the internet. The pictures were slowing down the HP a ton. Dh had to buy external storeage for all of his music because it slowed down the HP. So, it really depends on your needs.
I think next time around I'd like to try a Mac.
