Honestly, if you have an iPhone or any other Apple product and are willing to spend the money buying an Apple computer, I would. I have an iPhone, iPad, iMac and MacBook Pro that are all coming with me to Sheffield Hallam University in September. I went 'Mac' about 5 years ago and have never looked back. Windows computers do tend to lag a lot quicker after buying than Apple so I would definitely recommend Apple all the way!
Once you go Mac, you'll never go back!
