Would rather replace the display by myself and void the warranty instead. Or just buy a new one but my suggestion is, do not trust strangers, particularly Ledger employees, with your Hardware Wallet on their hands.
I also wouldn’t choose to send my device in for repair, I would try to fix it myself or buy a new one and smash the old one to pieces and throw it in the fire - $50 or $150 is not worth the risk, unless the device has never stored anything of value, or we got it broken.
I guess you're right, that developers always try to squeeze out the most out of the available hardware - even to this day. However, these days I see this mostly for example in AAA games, where sometimes at launch date nobody really owns the hardware to run them. But I feel like 'getting the most out of the hardware' should also mean making it run as good as possible, for as long as possible. I noticed in recent years smartphones running longer and better than in the past, where a 2013 application could slow a 2012 phone down to the point of 'unusability'.
