I use both Apple products and Windows. My laptop is a Macbook and my home computer runs windows. Before my Mac laptop, I used a Windows Computer.
In terms of strength and weaknesses, they both excel differently.
Pros of Macs:
Better Integration - videos, pictures, mail, documents, presentations, images, music, all of them can be easily accessed and arranged according to your needs and wants. I'm editing a school video? I can easily get pictures from iPhoto, music from iTunes quickly and easily.
Better battery life - Macbooks have a very long battery life. I have noticed that Mac batteries tend to last much longer, 4-5 hours longer than other computers. And this isn't some inkling. My friends and I had a test. 10 laptops, 3 of them Macs, the rest other laptops (albeit of different sizes) with internet connection and videos playing. All the Mac laptops outlasted the others by several hours.
Better connectivity - With Macs and an internet connection, without additional software, you can transfer documents among each other without using a thumbdrive or anything like that. It's useful in huge group projects that I have encountered with friends.
Incredible tech support - Apple tech support is fast and effective. It goes in, gets fixed and comes out in 3 days. The fact that both hardware and software are from the same company means that getting help is more streamline. My mother's as well as my friend's laptops took ages to fix.
Grapher - This is program made of making mathematical graphs (equations, stuff like that). It is far easier to use than any other similar mathematical graphing program. Although I only used this for 3 different occasions for school. Any person, whose job revolves around this will greatly appreciate Grapher.
It's also easy to find things (Spotlight)
Macbook Cons
Unable to play many games - Due to the issue of PC Games and Mac Games
Document type restriction - It is terrible to work hard on a powerpoint presentation only to have the file converted and a whole lot of things changed.
Mircosoft Words and Powerpoint - There are far better to work with than Pages and Keynote. Especially for complex Math Equations that need to be typed.
Adapters - Additional hardware is required for projectors and stuff like that since it is usually a windows compatible hardware that is present
That is all.
