Interesting response when you state that you may give Linux a try given Apple's direction and then you list what you like about Apple's laptop. I wonder why you're thinking that other then the recent 'post' by some complaining about the new Notebooks. I recently purchased a new MBP 15 (up from a 2011 MBP 13) and the build quality is still there, the design of the new laptop is really nice and the screen quality is excellent.

To top it off the new MBP have a awesome trackpad and are very quiet (least mine is I have the 2.6GHZ 16GB 256GB SSD model) and even while playing videos on Google Chrome (which use to really heat up my 13 inch) my 15 inch is quiet and cool.
