I have been using Pis for 7 years, my SD/uSD to Pi ratio is about 5 to 1 or even 10 to 1.
Actually too scared to count those SD's as I personally have over 20 Pi's.
SD cards fail, those plastic cases crack and break, uSD are better but I have snapped one.
Don't have as many USB sticks but they still outnumber my Pi's.
The USB reader write are less, maybe dozen+.
HDMI adaptors are even lower in number.
My collection of old 2.5"/3.5" Sata drives is growing
With USB 3.0 docks/caddies they are now usable for 4's.
If the only troll food is uSD card and not USB booting, well Pi's have always booted from SD or uSD.
USB/Net booting was a bonus on 3's.
With the boot EEPROM on the 4's other options spring to mind.
SPI, i2c even a Nand hat or Compact flash, IDE drive?
And it does look like we have a new bunch of trolls the Pi4 has sparked up.
Too bad the Pi4 is so good there is hardly anything to feed them.
But I only have this one 32GB uSD and it got filled quick with lots of games that just work now.
I only have two 32GB USB sticks. Time to get a few USB3.0 docks
Perhaps a big 1Gbs switch and big HDD for network booting Pi's?
These Pi4's mean a lot of network IT stuff needs to be learned.
Non stop learning.
