re: Convince me a Macbook Air is better than a Surface Pro 3

As someone who has both, (air for personal and SP for work) it really depends on how you intend to use it. I personally like the air better. One thing that would deter me from spending my own personal money on the SP3 is the buyback value down the line. With the Air, in two years I can still get around half of what I paid for it on the market, which helps with upgrades. The value of the SP is more than disappointing. Just my 2 cents.
