SSDs don't last forever. They're limited by the number of write cycles. Once an SSD has these depleted it's dead, and so is any machine with the SSD soldered in place. The new MacBook Pro is a throw-away piece of garbage.
This is the worst designed computer I've ever seen in my life. I had to get one of these to confirm compatibility of our software products on one of the new MacBook Pro's. Our software works, so guess what? I'm returning this thing tomorrow. Normally I'd be geeking out and playing with the thing and looking forward to using it for years to come, but this thing is a piece of rubbish.
Apple should seriously consider spinning off the OS X (excuse me, macOS) and Mac computer division to another, independent firm that understands how people use computers and what features they want. This thing, like the "fire hydrant" Mac Pro is a throw away. This is NOT a computer for professional users.
...I think it's time to start looking at BSD and Linux again.
