This stated intention and rpi.org's actions are simply not isomorphic. If they want to make Raspberry Pi more open, firstly, why do they publish only abridged (read: fake) schematics? [1] Secondly, why was rpi.org caught adding DRM chip…

> Secondly, why was rpi.org caught adding DRM chips to their optional camera addon board? to stop counterfeit boards. There are many _other_ cameras that you can use for the rpi, so its not like they are trying to block out competition. its to stop people making illegal clones and ripping people off. ( cough I'm looking at you amazon) see semi official explanation here: https://www.raspberrypi.org/forums/viewtopic.ph…

IIUC, you're saying that, for the Raspberry Pi designers, being open hardware is not only not a requirement, but there's actually requirements to be aggressively closed hardware in some regards?

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 why I switched to esp8266, smaller and 1$. Can fit a lot more in the same drawer.

Does anybody know if the ethernet controller supports PXE boot?

This blog post[0], says that it's not yet supported by the RPi 4, but that it's coming in a future firmware ugprade.

Is Wifi Antenna(Antena) part of the board? Or an external connector is used for Wifi or BT5. Cant find details in the specification.

The cheapest maybe, but don't I need to watch for specs and DRM features and everything?

As long as the cable supports your preferred "version" of HDMI, it should be fine, that cable supports 1.4. So it's not rated for 4k, but it will support all the DRM stuff.

Not that it's terribly relevant, as the board doesn't support the DRM stuff anyway.

As a fifty seven year old, I don't have 4k eyeballs. agree you have a limitation, not one which is holding me back since osmc does 720p just fine, for Olde telecine mp4s of B&W movies

If the screen is large enough about everyone gets 4k eyeballs.

I have a 4K-capable 40 inch TV in a standard living room (for Europe). 4K videos look slightly crispier than full HD ones.

While I could have a slightly larger TV, I think that for typical domestic use 4K's improvement is marginal because people are not sitting 50cm from the screen and room sizes are limited.

Really, so far the top benefit has been that I could tell my wife: "Look, if I move right up to the screen I can still see Jeremy Clarkson's individual hair strands!"

I'm a bit disappointed that they added type-D (micro) HDMI instead of just two more USB-C ports. If I need to use a dongle anyway (since I can't just plug inn normal HDMI) why not USB-C?

Preferably I'd like a version with 4 usb-c ports, 1 normal hdmi, and two normal usb ports. That way I could have it setup with just usb-c, but can still plugin legacy connectors when needed.

WOW, if USB3 and NIC are dedicated devices (not share one usb bus) this is amazing little machine!

According to the article the NIC is connected through dedicated RGMII - not through USB3.

Yeah, this seems like a very significant improvement for a lot of applications.

full specs anywhere? - VideoCore VI graphics, supporting OpenGL ES 3.x - including 3.2? GFLOPS? Does it support Android, Play Store etc?

You can install Android on it, and sideload the Play Store accordingly.

Not in a way supported by Google of course.

You can buy a pretty powerful full computer (networking, video, RAM, etc) that fits on a tiny card for $35. That makes it possible to build all sorts of fun things on next to zero budget - everything from robots to video game emulation systems and tv streaming boxes. The previous 3 versions were already wildly popular, but there were starting to show their age and to be significantly outperformed by Nvidia's Jetson N…

I always feel like I'm missing something. I don't have a single idea where something like this could be useful. Maybe because I don't care about "fun" projects and live a quit minimalistic live style? I must don't have (small) problems with no solutions. Then again, I've also never had an idea for an interesting software side project.
