Thanks for all of the responses. It looks like apple is highly recommended.
A couple more questions about apple.
1. I have heard that if you are on a mac and receive an email with a word attachment in it that you will not be able to open it. The salesperson at bestbuy said I would have to buy additional software for this. We didn't get into what software that was. Is it the microsoft office as mentioned above or does something like iworks open a word document?
2. The salesperson at bestbuy said pretty much the only difference between the macbook and the macbook pro was the bigger screen size. What are the other differences? I read on one of the review sites that the macbook doesn't have firewire but I don't know that I would miss it anyway if I really don't know what it is (I'm not really techie at all).
3. I live close to a bestbuy but the closest apple store is 1 1/2 hours away. Is it better to buy at an apple store or is it ok to buy from bestbuy?
Sigh. My former colleagues at Best Buy have not been entirely accurate in their info.
1. In order to work with Microsoft Office files on either a mac or pc, you'll need to buy Microsoft Office (which has versions for either) or iWork (which is for mac). Office for either type of computer is about $150, and iWork is $70. I have both on my Mac, but I prefer to use iWork. iWork will let you save any word processing document as a .pages, .doc, or .pdf file.
2. Screen size is one difference, but MacBook Pros are going to have bigger, beefier components - larger hard drives, faster processors, better graphics cards, etc. It's possible to get a MacBook with specs close to that of the MacBook Pros, but you really have to look at the specs for all the different models on apple.com to decide what you need. If you just do basic computing (internet, email, research, word processing) and you don't mind a smaller size, the regular MacBook is probably fine for you.
3. I spent 3 years working for Best Buy and really have awesome things to say about the company and how much they taught me, but if that's the info you got from them, you might want to look and see if there's an independent Apple retailer in your area that would be closer than an Apple store. I got my Mac at a local store called PeachMac before all Best Buy locations carried Apple in-store, and the people working there taught me a ton of stuff and helped me acclimate to my new computer a great deal.
If you go back to Best Buy, try to talk to the person that Apple staffs at the Apple display, not someone employed by the store (they'll have a different shirt). Some of the BBY employees won't know a great deal about Macs. If it WAS the guy in the black shirt that Apple staffs at the display that gave you that info, then run, don't walk, to the nearest place that sells Apple that is not Best Buy. Try googling "independent apple retailer *your location here*"
As to whether you actually need a Mac...you probably don't. But they're great computers, and I thought I was going to stroke out trying to get my brother's brand new Vista laptop to work last weekend when I brought it home to him. I'm very familiar with both operating systems, and Vista just makes me want to punch things. It's really a giant pain in the rear compared to working for a Mac, which is why I switched about a year and a half ago.
