I've got an HP no idea what the model is. Let me look. HP T60M283. I love it - got a good sale price. Had a Toshiba before but it only last a couple of years.
I've got a son who has a computer science degree and services my computers so I don't need to worry about service otherwise I hear Dell is good for that. Agree that processor speed and memory are key.
Mimi, the new computer should have wifi in it so you wouldn't need a card. Is your router wireless? If it is then you will be ok, if not then you will need to hook up through an ethernet cord.
I believe that Microsoft Office will work with Vista, I think that Vista is backwards compatable. My husband has it on his laptop and he has run on some older programs and not has had any problems. You should get those kind of programs already installed, but they may only be demos.
You can always get a wireless router. I have all our lap tops wireless, and i did it myself :) You can too.
what is your router for? Or are you talking about a modem?
