Okay, so it's obvious that some people are frustrated with the whole MacBook/Apple experience...but it's okay
So maybe fekimoki does belong in a Dell forum, but at least he's providing some sort of input from "the windows side".
Parker731, I was in the same situation as you just a few months ago. I'm a new college student, and I was making the choice whether to stick with Windows or whether to purchase my first Apple computer. Needles to say, I went ahead and purchased a Macbook, and it's awesome. I can honestly say that I'm never going back to Windows again.
Of course, it's not for everyone. However, based on your questions, it seems like a good choice. My 2.0GHz 80GB Macbook (similar to the one you're considering buying, minus the iwork) is great for photos, videos and school papers, and is extemely easy to get used to. I wouldn't know about the router, though; I use a netgear, but linksys should be okay.
You're hearing about a lot of problems in these forums, but don't let it discourage you. The people with the problems are the ones who turn to the forums for help, and they represent a small minorty of the millions of users worldwide.
Or, buying a Windows computer is always an option. Not exactly preferred in these Apple forums, but the choice is COMPLETELY YOURS! However, like most of the others here, I would recommend a Toshiba as opposed to a Dell. The price of the Dell right now might look attractive with all the school specials going on, etc. But if you go the windows route, Toshiba's quality is superior to Dell's and you'll be glad you picked it instead.
Best of luck!
