Someone buying used electronics on eBay has already decided that their time is worthless and the hardware doesn't need to be dependable out of the box. Which is fine, those are decisions a person could make, but it's just disingenuous to compare the value of one thing to another without taking the you are using someone's untested trash factor into account.

There are reasons to prefer a Pi over a used mini PC, but it is not reliability. The fact is that with Pis or PCs, _if_ you're still running after a week, you're highly, highly, likely to survive past the point of usefulness. Reasons to prefer a pi over a mini PC - easy access to GPIO pins; small(er) form factor; power efficiency; lower weight; still cost if you can work with zeros. Reasons to prefer a mini PC over a…

The biggest reasons to prefer a Pi over a mini PC: the documentation, Raspberry Pi Press, the community, the ecosystem.

Let's put it this way: you pop in your SD card, set up a username/password, a few other settings, and you end up with a system that already has Geany and Thonny installed. Go to Help -> Bookshelf and find all the issues of MagPi and Hackspace for inspiration and learning, and a couple dozen books like "Essentials - Code Music with Sonic Pi" or "Get Started with MicroPython on Raspberry Pi Pico". Search "Raspberry Pi Hats" and get a lifetime worth of reading and learning there, hitting just about any domain you could care about.

The vision of the Raspberry Pi wasn't to create a cheap, tiny PC, it was to create a learning platform, of which the cheap, tiny PC is the basis. More than any other computing device I've seen, it really lives up to that vision.

Surprised by the amount of negativity here. So many comments that are saying the raspberry pi isn't competitive in their market anymore and then post more locked down less open systems at 2x the price.

Seriously dude, why would you even want a new aarch64 SBC when you could buy a used NUC off ebay or just use a laptop you pulled out of a dumpster?

Because I don't just want a PC, I want a learning/hacking/making platform, with the ecosystem and support to go along with it.

A used nuc or dumpster dived computer doesn't have two magazines, a couple dozen books, official support and documentation and guides, and an entire world-wide community dedicated to teaching and inspiring me.

Through hole components resulted in previous Pi's being slightly slower to manufacture, the Pi5 only uses surface mount components which should increase Sony's build cadence.

The bottleneck has been component availability ("supply chain"), not manufacturing.

Upton talked about this in an interview. It's partly the interplay of manufacturing at this point, too.

When they have parts, they'd like to catch up with the backlog faster. Because the 5 doesn't rely on the robots that place through-hole components, its production can to a degree "overlap" with the Pi 4, basically increasing the total number of boards created per hour.

Having two SoCs that don't require the same machines also helps ease a bottleneck there.

TBH the thing I hate most about this category of SBC is the reliance on SD cards. They are both too unreliable to trust and so slow that they often bottleneck the SBC. Buying them is often a crap shoot too, I've purchased cards batches of cards from the supposed reputable manufacturers that were all over the board when benchmarked, and rarely did they hit the claimed speed spec.

It would be nice if there was just an improvement to reliability and speed of SD cards. I’ve used SBCs with eMMC built in (non-removable) and using them is a lot more complex compared to just flashing a new SD card image as needed. Based on the forums it takes a lot more effort for support as well, so from this point of view I’m not surprised raspberry pi has kept as cards as the main option.

The SD is the worst for reliability, but if it's like rpi4, you can put UEFI on the SPI flash and come up on non-SD boot devices without SD now. But that's all kind of crazy when cheaper, faster SBCs commonly simply boot to reliable, on-board, eMMC.

eMMC isn't that reliable. It's basically an SD card on a chip. Difference is they're more optimised for random writes than large files like most SD cards, but you can get such SD cards too ("High Endurance" models)

When was the last time the eMMC on your phone failed? They are very reliable.

I have had several SDs fail sooner or later since rpi1 though which is why I personally won't be using them any further.

I am curious to know how people here use their RPIs today, and how the RPI5 might help. I have had a model 3 for many years, which I enjoy tinkering with from time to time. I still haven't gotten over the novelty of having such small, cheap computer that runs Linux and does a pretty good job of it. That said, all I do is tinker with it. I turn it on, write a bit of code, marvel that the code runs, and turn it off. I'…

Until my home automation got complex enough to justify a faster, more capable machine, I ran all my home automation stuff on an RPi. I use RPIs as "data collection" units. I have one RPi outside with a cheap SDR to pick up all the neighbor's weather stations, which I dump to a MQTT queue and use to populate weather data in my home. I use another to collect GOES satellite images. I have 3-4 RPis that act as "Digital H…

Why is ns2 in the garage? Everything you said makes sense except for that.

The CM4 exposes a PCIe 1.0 x1 (Not sure about the revision) lane and can boot from an NVME SSD. It will be nice to have this capability on the Pi 5 with all of the other connectors (except for audio.)

I recommend booting Pi 4 and Pi 400 from external (USB) NVMe in an enclosure.

YIL a Pi 4B can run from a directly connected USB/NVME SSD. I've been using USB/SATA SSDs and all I have tried require a powered hub. Do note that I don't just just boot it up and proclaim "It boots - ship it"[1] I thrash it with various disk benchmarks and stress tests to be absolutely certain the SSD does not disconnect due to insufficient power.

[1] I suppose this is the H/W equivalent of the S/W engineer's proclamation "It compiles - ship it!" And I guess this dates me since S/W is pushed rather than shipped these days.

My gripe is that the original Pi cost $35 at launch and while they have made a better Pi...They have not made a Pi at that price ever again, even accounting for Inflation. Furthermore, increased power consumption and features have added big price jumps to the required Accessories. Now you need miniHDMI adapters rather than more common HDMI, you need cooling, you need more expensive power adapters. a fully set up Pi 1…

Do the modern Pi Zeros not compete with the original Pi at a stupid low price?

It depends on the use case. I have several I put around the house with sensors for IoT stuff. ESP32/8266 (and newer) devices would probably be less expensive since they don't need an SD card but are more work to program. The Zero has a full OS with dev tools built in. But for running a desktop, they're not so good.

They're not as cheap any more at $15US for the Zero W. I miss the days when Microcenter had them on sale for $3.14US on Pi day. They did recently have them priced at $10 to celebrate the grand opening of a new store.

I've had some really cheap cards fail but have mostly had better luck with name brands.

One of the things I do is to configure hosts to use the overlayfs (read only fileystem) where appropriate and that helps to reduce wear on the SD cards.

I don't use then where I want a responsive system and use USB/SSD or NVME/SSD instead.
