<p>Laptop. Without a doubt. Not up for debate!</p>
<p>Mac. Seriously, they're just better. I will never go back to a PC. I have NEVER had a virus or anything and I've had this for 2+ years (yet, it looks brand new, and still beats out most lap tops just coming out on the market in terms of specs and whatnot). I have a 15" Mac powerbook g4 w/ OS X 10.4.8, 1.67 GHz and 1 G and it is one amazing little machine. Although I wouldn;t mind a new macbook (but I have too many software programs on my computer to sacrifice).</p>
<p>Everything is more organized and easier to locate. No matter what it is on my computer, I can find it in a few seconds. Theres also a feature called Dashboard, which I cannot explain, but Apple can ( <a href="http://www.apple.com/macosx/features/dashboard%5B/url%5D">http://www.apple.com/macosx/features/dashboard</a> ). It's very useful. You name it.. any reference tool, you can get it on there, for free. Currency and metrics converting calculator, graphing calculator, dictionary, mini calender, virtual post-it notes, timer, ski report, yellow pages, multilingual translation, etc. All w/ one key tap.</p>
<p>My laptop has been through some hard times. It has fallen on the floor more than 50 times. Water, soda, liquid tylenol, you name it... it has all fallen into the speakers (which, despite only covering 1" x 4" of surface area, still play music loud enough to get me into trouble) and in the creases of the keyboard. Neither the keyboard, speakers, or aluminum frame seem affected at all. It's really tough. I wouldn't reccomend anything else.</p>
<p>Essentials: I would say a lot of memory. Think of all of the pages on Word you will have to save. </p>
<p>Programs: Microsoft Office (Word, PowerPoint, etc..) Those are the essentials, everything else can come later I suppose. I personally think iFlash (virtual flashcards) is an amazing program for studying, and it's cheap. But that stuff comes later.</p>
<p>Good luck!</p>
