There are many benefits to using Mac OS X over Windows; you’ve got better protection from viruses, the operating system is generally more reliable, and it’s very innovative and easy to use.
However, there are several disadvantages that you’ll definitely want to consider before making your choice.
Price
There’s no way of getting around it – Apple Macs are much more expensive than their Microsoft counterparts. You can get a decent computer for under $1000, but this just isn’t possible if you’re looking to buy an Apple product. You need to ask yourself if it’s worth that extra money.
Gaming
Mac OS isn’t designed with gaming in mind. You can play games on your Mac, but the performance is nothing compared to what you can get out of a Windows gaming machine, and the selection of games leaves a lot to be desired. This brings us to our next point:
Software Choices
Nearly all software - unless it’s specifically designed for Mac OS – is compatible with Windows. Unfortunately, it doesn't work the other way around.
Although you can still do nearly everything you could want to on a Mac, you’re a lot more limited on the software front.
Compatibility with Windows Products
You can import word documents and files from Mac OS to Windows, and vice versa, but it’s by no means a flawless process.
For example, if you write a paper for class on your Mac - with footnotes, line-spacing and headers all perfect – and then open it on a Windows computer to print, your formatting is going to be all messed up.
If you regularly have to switch between computers, it's best not to work with two different operating systems. It can get really frustrating.
