Played with a new Surface 3 at Best Buy today. $600 for the 128 SSD. Id pay double the price and get the new MacBook just so I wouldn't have to use that awful, plastic keyboard and trackpad. The S3 itself is pretty decent but that keyboard, ugh. Quality between the S3 and the MacBook is night and day.
Your exaggerating just a bit about the quality being night and day..... I own a 2015 rmbp 13" and I spent about a half hour messing around with a Surface 3 at the Microsoft Store. The quality of the Surface products is really good and has only gotten better with the Surface 3. The magnesium case feels sturdier than aluminum. The device exudes quality. The keyboards are quite nice as well.
Considering the S3 with keyboard is half the price of the rmb and has performance that isn't much worse, it is a pretty compelling offer. Additionally, the extended warranty you can buy for $99 covers accidents similar to having an iPad with Applecare+.
Personally, I would rather have an ultra portable device in the $600 price range that includes accidental damage because I know I will be walking around everywhere with it and if 1) it gets stolen or 2) it gets dropped, I am not out $1300 dollars.
