I bought a MBP15 with retina last year at launch and I am beginning to regret that decision. This might possibly be the worst mistake I have ever made in my life. I think a tablet and a desktop is a much more potent combination and much cheaper. The other day I was traveling and I brought my laptop with me. Everyone was enjoying their tablets/smartphones and I was the only one with a huge brick. I felt so embarrassed. Everyone was so mobile and they could easily flash their tablets/smartphone anytime anywhere. I had to lug this thing around for the whole day cause I couldn't leave a 2.2k device at the hotel. I bought this thing cause my mindset was so stuck in the 90ies and early 2000 when laptops actually were decent. But nowadays a tablet does everything better and at home a 27" monitor plus decent keyboard/mouse is more productive.
