Really? My only disappointment is that they switched the ethernet and usb
array. Arrggh, why?! Please don't tell me it was just to sell more

Or a VR display...

Because you can still build a 160-core server with 1GB RAM per core for a
lot less than an equivalent x86 solution.

Because robots with HDMI outputs can be very useful.

According to the Bitscope rep I asked, the Pi 4 should budget about 8-10W
per node. To me, that seems pretty amazing for a 4-core, 4GB RAM computer.
The Wi-Fi, BT and HDMI can all be individually disabled for ultra-low power
