Yesterday's "oops we bricked it remotely, no user interaction required" definitely doesn't inspire confidence - even though it was not intentional and was since fixed.
...didn't bother anyone until railroads entered the equation: astrology did take the difference into account, armies didn't move quickly enough to notice it: just keep adjusting to local time every day or so (even on horseback, any tactic is far more dependent on physical limits, so you're coordinating on the order of minutes, not milliseconds).
For railroads, even at 40 kph, an east-west train would be subject to time shift (not in the Lorentz sense, it would just keep switching "timezones" too quickly). Given that the primary security element was "this train is supposed to pass this set of switches between this and that time and wait there, else it risks colliding with that other train running opposite," both accurate timekeeping and geographically wider timezones were needed (as in "the railroad will use its own time, Prague's lunchtimes notwithstanding").
To pile on the anecdata: an all-nighter in my 20s was something feasible, even going through the next day (as in, day+night+day feeling fully awake, then resume usual behavior with normal night's sleep, and no further effects); at 25, this became harder, with a crash in the afternoon, at 30, an all-nighter meant sleeping through the next day, and currently just not getting at least 6 hrs of sleep will crash me the next afternoon. sigh
Reading external flash media becomes hard if you don't have FAT support. But agreed, anything internal should have used a sane filesystem (I know that's hard to find. At least an open one: I see ext* used internally, but FAT32 for removable flash).
Would have worked in 2000; nowadays, files >2 GB are an everyday occurence. (And don't even start with "but multiple-files archive"! This is not 1995, either.)
It matters a lot. You can squeeze impressive performance from a smartphone, too, but then you need to dump all that waste heat somewhere, plus you need to take battery capacity into account. In other words, in a desktop, power efficiency is commendable, but not critical.
Most USB flash disks I've seen (and I've seen many) are even nowadays mostly FAT32. "Portable drives" aka USB-to-SATA are shipped preformatted to NTFS, and only with the advent of SDXC did preformatted exFAT start to appear.
(It has to do with driver support, I would guess - exFAT works in Win7+, but as long as the world runs on WinXP kiosks (ugh), vendors go with the lowest common denominator. Note that a flash disk will go places - what's your car entertainment system running? Linux? Android? Windows CE? Anfient Embedded Monftrofity? Will it support exFAT? Unlikely.)
"Minor" depends on whom you ask: each time this happens, MS generates n angry support tickets...for me, not for themselves, of course: "the computer is broken again and I have lost all bookmarks and sign-in data, why did you break it again?!?" (The good news is, of course, that nothing is "lost" except for the default browser flag: resetting to FF fixes it...until next time)
As far as I am concerned, they can. But they are not bloody supposed to change it again, after I have changed it to something of my choosing. I am sick and tired of "yeah, so you have set your default browser to FF, but we know better than you what you want; so we have reset it again on yet another Patch Tuesday. Admit it, YOU WANT THE E!" (Consent, what consent?)
Decades old. The GWX consent brouhaha is decades old? Edge (not IE) becoming the default browser all by itself is decades old? Riiiiiiiight. Decades of consistent data, methinks.
