Cyclewhitney,
In general, the PC/Mac thing always degenerates into a flame war...but.. truthfully, both can get the job done. There. No flaming needed

Both platforms can work for you, but I find the biggest difference to be in the maintenance and upkeep of each respective system.
I find OSX to be much more "idiot-proof," a computer your technology illiterate grandmother could use, as well as still being a powerful platform.. You do pay extra for a little bit of "peace of mind" though. I like tinkering with things too, but in the end, you just want things to work.
However, be advised that if you are running Windows, you are going to need to go the extra mile to ensure you remain virus-free and be willing to manually configure certain drivers, etc. Virus-free/spyware-free is possible in Windows, though.
Additionally, if you want to retain "like-new" performance, there are a number of things that you must keep up with: i.e. disk defragmenting, occasional reformats. You will essentially never have to do anything like this with OSX. It will still be fine 4 years down the road, barring hardware failure.
So to wrap things up, if you get Windows, make doubly sure that you spend the extra time and effort and patience to keep it in top shape. I don't want any phone calls at 4 AM that go like "...um... I have a report due in 4 hours, but my computer keeps giving me the hourglass and freezing" :P
P.S. One last thing. The Macbook is much lighter and more portable than the home user class of Dell notebooks. College students travel, so it's a plus
