I would not touch an Apple Notebook with a ten foot pole right now. Since 2010 they have had a series of hardware problems which Apple has not rectified or in some cases in even acknowledged. I have a 2010 MBP that started kernel panicking whenever the Nvidia CPU kicked on, about 3.5 years after I bought it, when it was updated to Mavericks. Scoured the internet for answers. Apple had no clue. Most people had no clue. People were being told by apple to buy a $700 replacement logic board, which would go bad again in a few months. AppleCare did nothing about it. For a while people were using a little utility that would disable the Nvidia GPU, but that didn't always work right. Then an electronics engineer figured out that the problem was that Apple used an inexpensive capacitor in a certain place on the logic board, that can have a problem when the CPU speed changes. For a few hundred bucks he can solder in a higher quality capacitor and the problem is gone. This turned out to be the real issue. Someone wrote a little kext hack eventually that basically prevents cpu speed stepping from happening, and prevents the kernel panics, but the GPU is not running at full speed that way. I have been using mine every since using that kext hack, its getting too old to justify a few hundred bucks to fix the capacitor, but I might because I am definitely not going to buy a new Apple notebook anytime soon!
Now is this an isolated incident? Nope. Use google, numerous Apple notebooks came out since 2010 with weird problems that the geniuses at Apple's "Genius Bar" were clueless about and Apple did not ever really fix the problem or acknowledge it, people were just SOL. I will not touch Apple notebooks at all now, until their reputation improves, particularly one as expensive as this one! Mine was $4000+ in 2010 and it turned into nothing but a huge hassle. Lots of people suffered for years with kernel panics and not knowing what to do until that independent electronics engineer figured out it was the capacitor, a $3 part.
Never mind that Apple still refuses to embrace touchscreens and multitouch in their OSX computer products, their notebooks may look nice with a fast CPU and elegant looking case, but they are far behind the competition, priced in the stratosphere and you can expect no help from Apple when it turns out their fancy design has flaws.
