<p>Just a few additions:</p>
<p>Do I need to get Wireless Networking Cards or Routers (Only some buildings on campus are wireless enabled)?</p>
<p>Only if you think that you need it. Wireless is nice to have if you get a laptop. Centrino is just a bogus intel marketing name for a combination of a wireless card, intel chipset, and M processor. The card and processor alone will be sufficient (although Centrino is still fine).</p>
<p>How does the ethernet work? (What is it anyway?) and do I need to get anything to make my computer compatible with it?</p>
<p>Ethernet is a connection used to link a pc to a local network. The laptop probably has an ethernet card already, just look for it somewhere in the customization.</p>

Do I need the Windows XP Professional operating system? or can I get the regular Windows XP Home one?
[/QUOTE]
Don't listen to redski, Home should be just fine. However, you should check your school's networking pages.

How much memory do I need?
[/QUOTE]
512mb. If you want to game on a laptop, you're really going to have to spend over $1600, and you should get a desktop instead (a decent gaming rig can be built for that money, even beating a laptop that costs many hundreds more). I would instead put the money into a bigger screen, flatter laptop, second battery, faster processor, etc. 1 GB is an option, as is 768mb, but over 1gb is overkill. I have 1gb, but I ran with 512 for over a year on the same pc. I only used over 512mb on rare occasions, except in playing the most bleeding-edge games, and I do tons of multi-tasking.</p>

What size of battery?
[/QUOTE]
The higher the rating, the longer it lasts before it needs to be plugged in, and the more it costs. You decide.</p>

What about the hard drive?
[/QUOTE]
Depends on usage. The advice on 30gb and more if you download things seems ok, but I would recommend at least 40, because as you become more comfortable, odds are you will want to start downloading things.</p>

I would love it if someone would just build a computer for me and just tell me what to buy!!!</p>

Sure, but you need to be as specific as possible about your usage needs.</p>
