My data would be safe anyway because I have a robust backup strategy 😉
I have assembled loads of machines and spent my youth with a soldering iron in my hand, but my time is more valuable now than to spend it trying to prise open sealed up machines if they fail and, like it or not, the market is moving to commodity style appliances that are just going to get harder, not simpler, to open up (and not just from Apple)
There will always be a niche market catering for hobbyists and people who like to tinker, but I think it will be a rapidly shrinking one
