All, I was thinking of buying the macbook now and cashing in on some of these discounts/sales as I need a new macbook ASAP. I am still using my Mid-2010 Unibody and it has finally started to fail me. If I can get the 512GB 2015 Macbook at around 1100$, how much would it degrade over a 4 month period? My plan would be to buy the SkyLake Macbook when (if?) it is released. Thanks.
