Call me insane/apple fanboy/both who started out using a ZX spectrum 48k computer in 1985 and now using Macbook Pro 14" w/ 128gb ram. I luckily found a job that combines both love for computers, technology, and images/video. I used to upgrade iPhone every 2-3 years but life is short and I have now upgraded every year(14/15/16) as a lot of my work needs to be delivered very quickly and minutes count. I now edit 4k video on 15 Pro Max, upload edited video via google drive to client, sort/caption/transmit 50megapixel files and ftp them to client. I can leave the Mac at home now and that is a HUGE advantage. The USB-C port changed everything. Every cent I have put into apple gear has been paid back 5x and more in work. If I can get 15-20% faster chip and 2-3 hours extra battery life on 16 Pro Max it will be worth the upgrade. In the past I have handed down my phones to close relatives but this year since my immediate family all upgrade to 15 pro/max I will trade in the 14 and keep the 15 for gift it to sibling when I visit them abroad. For me the more expensive the tool the more advantage one can get from it for a certain amount of time.
