As much as I hate it, I think it makes business sense for vendors to solder. You can "upgrade" by buying new. I can't imagine the business value of such a laptop - esp now that hardware improvements are slowing down (for the typical use case)
Time for geeks everywhere to practice their de-soldering skills.
What about dead SSDs or RAM defects? You swap an entire machine just for those components? And what if that 512GB drive doesn't fulfills the requirements anymore?
