I did. I took a year and sailed. Sold my house and used some savings. I couldn't have done it if I had kept my house though. I was mid 30's at the time (40 now). I don't work in the valley though, I just do data and analytic design for corporations so finding a new job only took a week when I moved back to Columbus, OH after sailing.
While I did figure out I didn't love single handing a sailboat long term I don't regret any part of that year. I came back significantly happier than I was.
I switched when the surface book 1 came out (now on a surface book 2) but man I still miss the customizable trackpad gestures I had on my macbook pro. I don't recall the program I used but it allowed for gestures like three fingers with the index tapping to move to the next chrome tab to the left etc. I have been trying for years to replicate that in windows :(
