product details
Pros: The i7 processor is very fast, has 8 threads of execution (4 hyper-threaded cores) and the turbo boost kicks in when needed. It boots quickly, and runs applications quickly. I was able to install software and still use the machine without noticing any slowdown. It has a dedicated onboard graphics processor, with 1GB of dedicated graphics memory for gamers, I presume (I do not have any games to test it with).
Cons:
1. The fan runs continuously unless you turn it off in the BIOS. If you turn it off, it cycles, which is even more annoying. It cycles even when the laptop is idling (using very little cpu time). I did not notice the fan noise until I worked with it in my quiet office.
2. The keyboard layout takes learning. The pgup/dn are in the far upper right. The arrow keys and keypad keys are smaller than the QWERTY keys.
3. The power adapter has 120 watts output, and is huge and heavy.
Other:
1. touchpad has a lot of friction, but if you use your fingertips, it glides pretty well.
2. The battery life wasn't too bad, but I wasn't pushing the CPU or graphics.
I exchanged it after a week for the HP DV4-2170us model, which is cheaper and more portable.
