I really don't understand what the fuss is about: twice a year the clocks change, mostly automatically, and sometimes i even forget it happened. You just wake up, and go about your day. Zero impact from DST. Once a year you're lucky and have one hour longer to sleep, once a year you're out of luck and get one hour less to sleep. No big deal.
Much easier than having to rethink, reschedule, and renegotiate all times at some (rondom) moment in the year.
Luckily, here in Hong Kong, we have a constant UTC offset, but my poor colleagues in Sydney interacting with London and New York have 1-hour swings relative to UTC, opposite direction from NYC and London. So, Sydney has a 2-hour relative swing one way, and 2 hours back the other way, with 6 different days a year to take into account.
My brother spent a year and a half in New Zealand, and 6 months in Russia. Our mom spends half the year in Arizona, with no DST. Between family and colleagues, I found it easier to just switch to UTC, but obviously most people don't. Even after interacting with some pretty smart people for years, some of them in London and New York still get Sydney DST wrong, often getting both the dates and directions of the swing wrong.
Ideally, we'd all just do international business in UTC, but that just seems too difficult for most people, so getting rid of DST would at least make things a bit easier. Granted, my dealing with 5+ time zones in 5+ countries every work day is a bit unusual. Poor Kiwis: most people think Wellington and Sydney are in the same time zone.
