Ok, so I have been a Mac user since 2006 with the Mac Mini and Macbook, before that I have used Windows since the 3.1 version so that might get you to understand where I am coming from. In 2005 I got a nice virus and everything I had stored went to ******, this was with an updated anti-virus software, so after that experience I looked around for something new, I was tired Windows as you can imagine. A friend of mine recommended OS X. I looked a little online and it presented itself very nice and was not prone to viruses so I went and bought myself into the Apple-experience. Fast forward till yesterday, I got my Macbook Air: 2014, i7, 1.7GHz, 8GB, 256SSD. Let me first explain what I use this for. I have my own company, I do a lot of work in Excel, Word, Safari, Mail and Photoshop. This thing is F A S T. I have all apps open at ones, no lag or anything, I can listen to iTunes at the same time without anything slowing down.... and it is S I L E N T, you hear nothing, only time I heard the fans were when I installed Yosemite (clean install of course). Carrying this beast is so easy, super slim, super light yet super sturdy, this thing is a amazing. I just wanted to come on here and say this, it´s an amazing machine. I first thought about buying the Macbook Pro with 2Gb Dedicated GPU, but for what? From what I hear those retina machines can get warm much faster and prone to problems down the road. My Macbook Air is P E R F E C T! 5 out of 5 whatever, these things are amazing. /Thanks from Sweden.
