Re: DSI display @4K ?
HDMI only. The DSI is as before.

SD cards are still the best way for the 'desktop' Pi, cheap and easy to use. And yes, we are entirely aware of lifetime issues, which you can mitigate hugely by avoiding writing to them unless you really need to (ie logs to tmpfs etc). Some people have had Pi's running for multiple years with no SD card issues.
The cost of adding EMMC would be a real problem - margins on devices like this are small - we don't want to make them even smaller.
If you want industrial, use the compute module, which has EMMC. (No Pi4 version yet).
That said, there is some flash on the Pi4! Not a huge amount, but it contains the bootloader. In the long time, it MIGHT be possible to leverage that, but that is subject to change.
Cannot comment on the Google stuff, we are not Google.
And that already exists. This launch was licenced, and that licence included a large section on the deorbit requriements, as do most other launches nowdays.
Asd it happens, even dead, these satellites will deorbit within 5 years due to atmospheric drag. If they are not dead they can be deorbited much more quickly as they have on board SEP thrusters.
A little Google goes a long way. These are LEO satellites, and the licence to launch them also included extensive requirements on deorbiting. And beause they are LEO, atmospheric drag will bring them down quickly upon request, and within 5 years I belevie if they are completely dead and cannot deorbit themselves.
No one want to duplicate the Space Shuttles capabilites, because those capbilities are not useful any more. SpaceX have the Dragon2, which will do most of what the SS did at the end of its life (deliver people to the ISS), which is exactly what it was designed to do. The dragon 1 also outperforms the other cargo capsules in that it can return a decent mass from the ISS. The SpaceX reusable system is massively cheaper than the SS, but does an awful lot.
And of course. SpaceX have Starship, which will outdo the SS if it works.
It's a minor point, but it's Raspberry Pi (Trading) that does all the development (HW and SW) of Pi's and sells them. The Raspberry Pi Foundation is the educational side. RP(T) is a wholely owned subsidiary of the RPF but is quite independent in its day to day running. Now also in a different buildings after the Station road office was flagged up for demolition.
Those performance figures do not add up at all. I would expect a A72 at 2.3G to be at least 3-4 times as fast as the A53 at 1.4G on the Pi3B+. It should be about twice as fast just from the architecture upgrade, then add on the extra clocking.
As as for the website comparison - what utter bollocks. That more related to memory, and networking that the CPU speed.
What DaveK said. Laptop, docking station, a few extra monitors, keybopard mouse (because laptop trackpads and keyboards are horrid). Sits on desk at work, bring it home every day, but don; tuse it unless I HAVE to, makes it easy to work from home. Runs windows but most of the real work done in Linux in virtual box. Actually at home right now typing this, simply plugged laptop in to monitor, now in exactly the same environment I was yesterday when I left work. Laptops just work (mostly)
I've tried doing work stuff on a tablet, admittedly a small cheap Samsung, horrible. For general net stuff, absolutely fine. Not for work.
It's not just the download time. When doing an update it can take ages to install, so much so that people have thought the device had locked up.
If you add up all the extra 700MB over all the Raspbian downloads from the last 5 years, (100 million? Dunno, might be worthwhile finding out) that adds up to, er, quite a lot of wasted bandwidth.
TBH, there has't been that much grumbling. Engineering preference is to have it in the repos rather than installed by default, as it's a huge chunk of the image that a large percentage of users don't need. As a user of Raspbian, but non-user of Mathematica, if you don't remove it, then when an update appears its takes a load of time to download and install it.
Having it in the repo means those that want it can download it. Those that don't save 700MB of bandwidth.
Unfortunately its not easy to identify the problem boards, the chips don't have much in the way of ID. Keep an eye out on the blog over the next couple of days - more detailed information to be published soon.
Not sure about the channel - certainly the next production run will have the problem fixed, IIRC it's delayed until the fix is finalised.
The MPG2 thing is a PITA. Unfortunately there are still two regions where the licence is required, and since we do not region encode the Pi we cannot guarantee that any Pi will not be used in those regions. We would dearly love to get rid of the whole thing - it costs us more than we make back, to run the licencing system.
It's not random, it's if you short out certain pins on the GPIO its can kill the PMIC. Its more comon on 3B+ becuase its the only one that uses a PMIC.....
Just dying is extemely rare, but can happen. Just like any other equipment. If it dies under warrantee, get it replaced.
Wow. Quite the rant.
Just to inject semblence of truth in, we have never provided full schematics of any of the Pi boards. so to say we are geting less open is an exageration. We have had to change a little due to to becoming more competitive - ie we need to maintain our competitive advantage to remain in business. Easiest way to do that? Keep certain aspected under wraps.
Mising component labels is a cost saving measure, and what we can fit in limited space. Not much more to it that that.
We do not have an elistist atitude. We welcome anyone to contribute to our linux kernel, our documenation, our projects etc. As we do get some really good contributions in all those areas. What we cannot do is open csource the GPU binary blob, because we do not hold the copyright on it - that is held by Broadcom. We release what we can.
We screw up, everyone does. This is a case in point. But we've come clean, which is more than most other companies. Be nice to understand what you mean by your last paragraph, taking in to account this exact example.
Anti-Tesla anti-Musk forces are out in force today.
I'm more of a optimist. Tesla will fix production (AFAICT, it's pretty much already fixed), Model 3 will continue to sell shitloads, autopilot will get better, other manufacturers will all release full electric cars in the next 2 years, Tesla shorters will lose their hats (good, shorting stocks and trying to force the stocks down when they won't do it by themselves is a pretty offensive way to make money)
Here's a good read. https://www.dailykos.com/blog/Rei
