However, given that there are also two USB3 ports, couldn't I drive a total of four 4k displays ?
I don't know if USB3 can drive 4k @ 120hz, however ...

Why? What do you use composite video for? I think the last time I used composite video for anything was 10+ years ago.
Not OP, but I love the composite output. I have a raspberry with retroarch connected to an old CRT and an arcade stick. Old arcade games with a lot of dithering just don't look the same on an LCD. (Some emulators now come with some decent CRT filters, but It's still not as good as a real CRT)
I ordered a 4GB Pi4 which seems to have advantages, and I assume the availability of Arm64 images will sky rocket?
My young son got a 3B+ for Christmas and it has provided no end of entertainment. He discovered Minecraft early on and that ha led to him starting learning to code so I think that was a great investment, probably the best ever.
What does he do with it? From what I’ve seen, most people throw these in a drawer instead of find educational value in it. Would be interested in anecdotes where it led to something positive and what approach worked out.

I have to confess that I have never even booted up my Pi-3. Now I wonder if it is worth booting up the Pi-3 or should I wait till I get my hands on the Pi-4. That way I don't have to think of upgrading.
The Pi 3 is no less usable than it was before the announcement. Why bother getting a Pi 4 when you haven't found a use for your 3 yet? I still use a Pi 2 with no complaints. One downside to the 4 is that it is moving from the low power to laptop realm in terms of power consumption which was my main interest in them. If top performance is what you care about, the Raspberry Pi is the wrong place to go looking for it.
Can't wait to buy this, boot it up, play with it for four hours, then stick it in the same desk drawer with the other Pis I have bought over the years. (The upgrades look great, just my attention span is not so great)
That's silly. RasPis are stupidly useful. I've got: * A Zero W hooked up to a PM2.5 to do air quality monitoring in the house. Just bought a couple more sensors for it (VOC, eCO2, etc), but haven't hooked them up yet. * A 3B+ running the UniFi controller for my home network. * One is running a custom Hue automation I built to shift the color temperature of the lights throughout the day. * One is built into an interne…

> compact home cloud Can we just start calling them servers again?
The distinction in actual usage between using cloud, server, and homelab to describe their setup seems to be rooted in their purpose. * Home Lab :: Running a partial/full enterprise IT stack for fun and education. * Home Server :: Running primarily internal services like file storage, backups, media streaming, home automation, maybe some light networking. * Home Cloud :: Running primarily external services on the pub…
If does go down then it's not cloud, no matter what hardware you're using.
In general, my rule of thumb is: what's the upper limit, the capacity or your wallet?
If the limit is the capacity, then it's HA.
If the limit is your wallet, then it's cloud.

Finally! First RPi SD card performance upgrade ever. Doubled, so I guess around 40 MB/s. Still a far cry from fastest SD cards that can both read and write over 250 MB/s. Hopefully RPi4+ will improve on this. :-)
People have spent however many years since the release of the last pi suggesting improvements. It's announced today offering basically everything that people were asking for, and you are already planning for the next one?
I'm very happy for RPi4 SD improvements. Until now, RPi has had same lacking ~20 MB/s SD performance from the start. AFAIK, this is the first time ever there's been any hardware improvement in this regard.
I've had a microsdxc card with 90 MB/s reads and 80 MB/s writes since early 2014. Some current cards can read & write more than 250 MB/s, so there's still room for improvement.
As 95-99% of all RPis boot from (micro) SD and use it as primary storage, I'd say SD performance is a rather fundamental (often ignored) aspect of RPi performance.

The Raspberry Pi 4 B uses ARM VideoCore IV. As far as I can find HDR will only come in the updoming VideoCore V. So no. No HDR yet.
That's really too bad. It makes the 4K support useless for building an HTPC, which is a common use for the Pi. As far as I can determine, several of their competitors already support 10bit decoding, although specifics (about stable HDR support) are sometimes hard to come by.
You people are never happy, aren't you? You're still getting more stuff for basically the same price...
