My cousin is gonna send me a Macbook (he had the early 2008 model, and he's getting a new one), but i already have a Windows laptop.
Here is what i use my PC for:
-minor gaming (Half-Life, CS, Minecraft)
-school work
-making YouTube videos
Added (1). I don't care about the OS, i lived with Windows XP 'till 2015. Macs can run Windows, who said they can't?
What is the question?
Mac vs Windows is a religious argument.
I'd just say a 2008 MB is kind of old. Not sure it will run the latest MacOS?
Macs aren't the best for games, not sure if those particular games are supported on Mac?
If you play games, you don't want anything to do with a Mac, especially a 2008 model. But, you know, who says you can't keep both?
I'm more of a fan of Mac. This is coming from somebody who has used both. But 2008 is pretty old. Probably won't run the latest versions of MacOS. Also, Macs aren't the best for gaming. I know Minecraft works on Mac, but I'm not sure about the other games. You can always test it out and not use it if it doesn't work for you.
The mac can do all the stuff you mention, and is largely immune to malware. However OS-X (mac) has a lot of its own problems. Macbooks from 2008 and older are subject to a malware that can take control of the camera.
