I've used Windows my entire life and have never really had any complaints about it, but I'm looking to buy a laptop and think I might like to give Macs a try. Unfortunately, I know absolutely nothing about them, so I hope you all can lead me in the right direction . First and foremost, I'm looking for something cheap, preferably less than $1000. I noticed that the cheapest off-the-shelf Mac laptop is right over $1000, so I wouldn't mind looking into older models that might fit my needs. I'm looking for something light and easy to carry. Some of my friends have laptops that are so clunky they may as well be carrying around their desktop. I don't want something so small that I need to pull out a magnifying glass to see, but you get the idea. I'd basically be using it for web surfing, typing notes in class, and basic music/movie playback. There's a chance I could use it for video editing, but it isn't a primary concern for me. I am a physics students and I will be using a few processor-intensive applications like Mathematica and Matlab, so I'm not sure how well those types of program mesh with Mac software/hardware. One question I had: is it possible/easy to network a Mac laptop with my Windows desktop for file sharing? Also, please help clarify my understanding of Boot Camp. It lets me install both Windows and Mac OS on my computer, and choose to boot one of the two whenever I wish? Basically, I can run my Mac like normal, but always have Windows around in case there's something I can't get to work right on Mac? Do I need a certain generation of laptop to be able to run Boot Camp? So, what type of laptop would you recommend for me? I am very computer knowledgeable, so don't be afraid to throw out technical terms. Thanks!
