@shewolfnm,
I have a HP 17" laptop, dv9700US, and I've had it for about 6 months. I love it, and I've not really had any problems at all with it. I bought mine as a desktop replacement and I use it mainly for Web surfing and everyday things.
I like Windows Vista, and the laptop has more than enough memory to handle it. Except for serious gaming, I think the laptop can easily deal with most other software applications. I can't comment on battery life because I really don't generally run it only on the battery.
I use an optical laptop mouse rather than the touchpad. I'm not sure a wireless mouse is necessary. The one I use plugs into the side of the laptop, and easily unplugs and goes into the laptop bag if I want to go somewhere. One disadvantage of the 17" screen is the size and weight of the laptop--it's heavier and bulkier to tote around. I don't plan on travelling around much with mine, and I wanted the larger screen.
I have another computer, a desktop, and that computer, and my modem are both connected to a Netgear 802.11g Wireless Router. The first time I started my laptop it immediately picked up the wireless signal from the router without my doing anything. The laptop has built-in wireless capacity, so nothing has to be connected if you already have a home network. If you don't have a home network, I imagine you must plug your modem directly into your laptop. However, if you take the laptop out, to any place that has a wireless signal, the laptop should be able to pick that signal up.
If you are having problems with the laptop picking up the signal from your home network, call HP and ask them for help. I have called them once with a question and had no difficulty getting a speedy reply.
So, I'm very happy with my HP laptop. It's loaded with features--many of which I haven't even had a chance to use yet. I really have no complaints about it at all.
