This is a question to do those who do it? I know you have your typical engineer who needs to have the best technology. But for those who are your more average business user or just a casual user, what benefit are you getting from upgrading to a newer MacBook Pro every year? I am curious because I look back a decade or two ago; whether PC or Mac, you kept your computer for a long time. A lot still do, because I come across the threads from those still using a 2008 or 2010 model Mac. I personally look at my own usage behavior and with the advances in hardware and software, you can keep a machine pretty much for 5 years and get those free macOS upgrades without considering a new Mac. Sure, there might be some unique advances like Metal 2 improvements, HVEC that will require the 2016 and 2017 Macs. This seems niche though. So, for those average users, whats behind your strategy for upgrading every year and how do you handle getting rid of the older model?
