it is vulnerable to a battery wearing out
Do you even own one? They don't have batteries...
LMAO

No, I don't own one.
The link you provided "for more information" doesn't talk about power generation, it only says there is no battery. If the fob has a screen it has to generate power...so it must have some source to generate power. Even a watch stops ticking...any thoughts on how Trezor keeps ticking?
I plan to hodl some coins for a very long time. I don't want to pick up my Trezor one day in 10 years and find a blank screen.
