After a lot of thinking, the MBP 2015 '13 is cheaper, has ports, same speed, more reliable, and longer battery life. Is there anything I should double consider before I do this? 1-I will order from Apple.com , I heard you can get better deals else where , is this true? 2-I never bought a laptop online, are they safely packaged? 3-There is an option to upgrade the CPU from 2.7 to 2.9GHz for $100, is this even worth it? 4-The 512GB option will cost me a cool $1700 no taxes, am I missing something because this seems more expensive than a high end 2016 Windows Laptop. 5-Do they ship international?
