Preach, sister or brother.
In 2011, I bought a top of the line 15" MacBook Pro (4GBs RAM, 750GB hard drive, 2.2GHZ quad core i7 CPU, SuperDrive, Firewire 800, ThunderBolt, SDXC card slot, non-retina dispay) for $2,200. It was future proofed, which for my use case means the ports and CPU would last me at least five years, and I could upgrade it as needed. And upgrade it I did. It now has 16GBs RAM, I removed the SuperDrive and replaced it with a 1TB Hybrid drive, and also replaced the 750GB hard drive with a corresponding SSD. All this for about $600-$700, relying on sales. I could upgrade it even more with faster RAM and dual SSDs.
Upgrading the 2016 15" MBPs does not look like it's an option (it looks like you can upgrade the non-strip 13" MBP), so if I want to ensure it lasts 5 more years, I'd need to pay out over $4,200 for the top of the line 15" MBP. And even then, since I'm currently pushing what I can do with 16GBs of RAM, I know I'll actually need 32GBs in the next year or so and that is not an option for the 2016 MBPs. So, top of the line for me, is near twice as much, with a higher risk of needing a new computer before five years are up.
