I have a 2 laptop questions., Hope you can help(: Options

[StubbornFemme]

So, I just ordered a laptop at Costco.com because I need it more than ever now for college. It's kinda late for me to get one but I need it when my stupid sister is hogging the home comp. for Myspace..but anyways...I NEVER OWNED a laptop before so clear some questions for me:

1) The thing I hate about laptops are the mousepad crap on the computer, could I just hook up one of my spare mouse I have from my home computer to use on the laptop?

2)So, I have SBC Yahoo DSL for our home computer..when I get my laptop..do I have to buy extra phone line to hook up to mine...or what's the deal w/ it? I have used a laptop before, it was my step-mom's but I just hook up the phone line to the back of the laptop but I'm wondering how do I do it if my sister is on the internet on the home comp. and I WANT to get on it too on my laptop...is that possible?

Thank you to those reply back w/ great advice-no critism!

Laptops!

1) Yes, you can just buy a mouse and hook it up into your laptop's external device. I have one of those, i hate the fingerpad too.
2) Phone lines are optional. Laptops = wireless! So your laptop should have wireless enabled. Which means you'd have to purchase a router (check out Best Buy or something) and you can hook that up with your DSL and access internet wirelessly. You can still use phone lines; on laptops, there's a port for that too. But if you can put your laptop anywhere in your house and access internet from there, why not?
