It is. You can't easily fit a Raspberry Pi 4B in a case that thin, keep
the interfaces AND stop it overheating. Like I said in the meeting: it's
a true home computer because it has a giant heatsink. In the old days,
the heat came from the voltage regulators (linears like 7805s aren't
thermally efficient at all) but now, it's mostly from the CPU.
The CPU is also a new beastie that runs at 1.8 GHz instead of 1.5. Yes,
it needs a new firmware blob to manage the CPU.
The Raspberry Pi Foundation never announce next products, so any 8 GB
version will have to wait until the new year. Like the old home
computers, xmas sales are everything for this machine.
(For context, World of Commodore used to take over an entire exhibition
centre near the airport. I'm told that the December 1983 one took
something like $6 million in sales ...)

I can only think of three groups who still love 'em, but they're pretty
niche:
1) Retrogamers who obsess over screen latency;
2) Retrocomputing types who run computers with ancient video standards
like Amigas and the Apple IIgs;
3) The good folks in and around Elliot Lake, ON who depended on the
yttrium extraction from the mines there. Latterly, the uranium deposits
apparently made more money from yttrium byproducts for CRTs than any of
the radioactive stuff.
cheers,
Stewart
