We use HP at work and I have had several HP laptops at home. All worked fine and had no problems with them. The only thing I did upgrade was the RAM and that all went just fine. BTW, I usually buy used instead of new. But now, I have a Dell Inspiron 1720 laptop with 17" screen and full 1920 x 1080 resolution. I added a second hard drive and upgraded the RAM. I also bought this one used and have had it for about 5 years now. At one point, I sold it because I wanted a smaller lighter laptop. Bought an HP and the lower resolution and smaller screen were just too hard to get used to. So, I called up the person who bought my Dell, and asked if they would sell it back to me. I offered more than I sold it for and thankfully, they did sell it back. So, I guess I am saying I am a real Dell lover now.
