Rubbish. They do. My daughter's school has a pile of knackered Pi's that the teachers don't have the time and budget to fix. Broken connectors, duff microSDs, bricks. They don't use them now, preferring python on windows.

> duff microSDs Do you mean the microSD cards tend to wear out, or that they’re DOA? If the former — I’m pretty sure there’s an option to load RaspberryOS into a RAM-resident mode (like a live CD) where regular OS usage won’t hit the disk at all, and only a “Local Documents” partition is mounted writable, with nothing configured to implicitly write to it by default. If the latter — trust me, the same is true of eMMC,…

> If the latter — trust me, the same is true of eMMC, or any other Flash media ordered in bulk quantities. You just have to QA them on arrival. Set up an RMAed-parts box with a shipping label in advance; you’ll need it.

SD cards and USB flash drives are manufactured with lower-grade flash memory than SATA and NVMe SSDs. The stuff that wears out in RPi usage is the stuff that was rejected for desktop usage. So having a large failure rate is not the only option, if you can expose a SATA or PCIe port. It's a little disappointing that they cannot even offer end users that upgrade path.

This blows my mind. I know, it's much more incremental than it is revolutionary, but I think the form factor achieves a much greater degree of access for many people than a typical Pi whose bare hardware may be a lot more intimidating. Now, it's "just" a computer, which happens to expose a 40-pin connector for the standard Pi hardware fun. And unlike other options you might find, this has the massive built-in communi…

Having a flatscreen TV is a very high priority for poor people in the US.

My only wish for v2.0 of this would be an integrated touchpad so I don't have to use a separate mouse. Similar to a Logitech K400 wireless keyboard. I don't know how many times I've been in a situation where it's challenging to find a surface to use a mouse on when I'm working on a Pi project. Workshop, electronics bench, just doing something real quick on my lap, etc.

If we're making a wishlist for v2 we may as well put "full sized hdmi ports" on there.

Is there a games/app market like Steam available for non-iOS/Android ARM-based devices? I would love to be able to set this device up for my younger kids, allowing them to play Minecraft and Oregon Trail-style edu-tainment type games while leaving the device open for exploration and tinkering. The walled gardens from the major players are blocked off, and distro-based package managers aren't really suitable. IMHO, on…

Almost none(prob some Foss one). Using qemu-user you can run amd64 code on arm. Opengl is going to be a issue though.

A flatscreen? as opposed to a CRT?

Most people have a TV. The cheapest TV you can buy has an HDMI port , it's like 70$.

I could see a kid plugging this in , doing his homework and after school mom and dad can watch the Pistons.

Can you use the keyboard.... as a keyboard for other computers?

Yes, I think Gordon Hollingsworth from Raspberry Pi has posted somewhere specifically how to do it (maybe in the comments on the post on the Pi website?).

Found it! Merci :)

>It would be possible to do this, but you’d have to run a simple buildroot SD card which runs a suitable dwc2 OTG HID driver to pretend it is a keyboard…

Otherwise, you can use the Pi 400 as a Barrier server to the other computer… See my other blog post for details!

I was lucky to get a pre-release version to test, and I decided to tear it down before I started trying it out. I posted this blog post with detailed pictures of the insides, and some more details and performance benchmarks: https://www.jeffgeerling.com/blog/2020/raspberry-pi-400-tear... There are also a couple videos linked in the post, if you're more visually-inclined. Fun fact: the Pi 400 (and Compute Module 4) bo…

This is slightly disappointing, I was expecting it to be some kind of case for the the Compute Module (or at least for the RPi4. I don't know if it's unrealistic, but it would be nice to have some sort of upgrade or repair possibilities.

That seems to more or less already exist: https://shop.pimoroni.com/products/raspberry-pi-keyboard

Can we please have a Pi without a crappy storage interface. It's either a microSD card or something dangling off USB. An M2 SATA or NVMe would make this credible but 99% of the problems I've had with the Pi platform is storage related, either being knackered microSD cards, terrible performance or USB power problems.

The RPi 4 has USB 3 + UAS which is actually quite decent. I use it for Aarch64 development[1]. It boots and runs entirely off the SSD, and the performance is not spectacular but perfectly usable, and being it's a regular SSD it should be at least as reliable as a laptop. It also has a firmware bug where it cannot boot unless there is an (empty, unused) SD card in the slot, which is annoying! [1] https://rwmj.wordpres…

I boot a RPi 4 via PXE (or rather, the RPi version of PXE, which is decidedly non-standard, meh). No SD card in the slot. No problem. Are you on the latest firmware?
