I have two Macbooks currently. A 2011 Air and a 2013 Pro. Both work fine, although as I use them mostly for FCPX editting, the Air is kind of slow with current 4K footage. It is my travel laptop, however, since it is small and easy to travel with. I have resisted updating the hardware because of the lack of ports on the new machines. I think the small ones only have two USB C ports and the large ones have 4. I typically need a minimum of 3 ports, sometimes 4. (power, external hard drive, SD card input, sometimes a 2nd hard drive + headphones). I'm throwing in the towel now and suspect I'll just have to travel with a bunch of dongles if I want to update machines. So, question is... what is the best slim MacBook to meet or exceed the performance of my current MBP? Currently I have a late-2103 15", 2.6 Ghz Intel Core i7, 16 GB 1600 MHz DDR3 with the NVIDIA GeForce GT 750M 2GB Intel Iris Pro 1536MB. That's a mouthful. Last time I was shopping, I came close to buying the latest gen 13" Airs that were still available via refurb. At least then I'd get the ports I wanted. Appreciate any tips and thank you!
