I'm having the same thoughts, Buster wasn't quit ready for prim time IMHO.
Depends what you mean by prime time?
I'm finding mine works pretty good, but I am not pushing it, windowed YT not full HD yet.
32GB card fills up real quick as lots more stuff just works now.
Tried external 2.5" USB Sata HDD but 2.5Amp PS is not enough?
One of my old B+'s runs with externally powered USB 2.0 Western Purple for security cam storage.
It has done so for years, on it's 3rd HDD, been running 24/7.
So external powered USB 3.0 storage on the Pi4 as a Desktop PC that stays in one place.
Buster works pretty good if you can remember how bad that first version of Raspbian was
It's not perfect but how many people are complaining?
How many Pi4's have been sold so far, 200k?
If it was really bad there would be much more whinging.
it appears that the firmware and Raspbian were both released pre-Alpha quality.
Well Raspbian is not exactly Alpha, Buster is just a newer version that has more mainstream Pi stuff in it.
There is a 4.19 kernel post that has been running for a long time, lots of things found and fixed in that.
Software can take x amount of time, in the mean time Pi4s are filling up the warehouse at 15K/day or was that 15k/week.
There must have come a point when the decision maker said, "Ok, it works and this list of known issues won't affect most users, let them out".
We get them early and nit pickers say it's not perfect?
Software is never perfect, not the big bloaty stuff we get these days.
"Release early, release often".
I'm dancing on Rainbows.
