I'm looking to upgrade to a new laptop since my current one is about 5 years old. I'm just curious how the new MacBook will compare to my aging Retina MacBook Pro? I honestly don't need the power of the Pro line and I love the form factor of the new MacBooks, but I'm really curious if it'll be significantly slower.. or if the 5 year gap will cause it to actually be faster with the newer hardware? Any input would be appreciated. Thanks!
