Ha, ha, yes, I'm a granny. I have two grandsons, ages 18 and 20 years. 
Apple Mac's are good. I have one. I've used Apple computers since the mid-1980's. I also have Windows computers. I'm comfortable using either one.
It depends on your budget and needs. If you can afford a Mac you might want to do that. If you can't afford one, the Windows computers are fine for most people's everyday uses.
It also depends on how flexible you are about learning a new operating system. Mac's and Windows are different from each other. Also, if you stay with Windows, be prepared that Windows 8 is different from Windows 7. You can learn and use any of them but just be prepared for the difference.
