Hey. I currently have a MacBook Air 2014 model. I'm an iOS developer. Have loved using this machine but looking for something faster. Have put off buying a MacBook Pro but feel like I need an upgrade now. Is anyone actually happy with their machine? Here is what I hear I get for £3600 odd: (2.6 GHZ i7 15", 32GB, 1TB) 1.) Speakers that crackle 2. ) A keyboard that is rendered useless by dust 3.) Light bleed around the casing of the screen 4.) Uneven color balance on the screen (pink on the LHS) 5.) A machine that runs much hotter and will make more noise than my current one 6.) Random OS bridge crashes Have I missed anything?
