My older one is HP dv9730us. Shows its age. The current one is dv8t 1100 featuring i7 720QM processor.
I like the speed of the new laptop. A bit faster. But it has an issue that the wifi button will go on and off randomly (and the treble/bass softkeys as well). It is really annoying. It is a design flaw of some sort. I am really disappointed that HP won't acknowledge the problem and won't do recalls. So far I have returned this new laptop to HP once... screen connection issue. The last HP laptop dv9730 I sent back 3 times. 2 disk drive problems and 1 motherboard problem. My confidence in HP laptop is not very high. Their desktops are better. I had 4 HP (Compaq) boxes and all worked well.
