Pi's refusal to drop a USB-C on Pico due to cost increases is a terrible call IMO.
I seriously cannot fathom being someone doing development who wouldn't pay $0.50 extra to purge the last micro USB from their desktop.

#12Earlier quoted context omitted.
Performance per Watt still outranks any other (quasi-)mainline linux device
Do you have a reference for this? Looking around, I see it being beaten by other ARM SBCs, and even low end Intel devices. Many years ago, I measured performance per watt of the original Raspberry Pi when they were still relatively new. The performance per watt lagged behind even a beefy Intel box since the original Raspi was so slow that it destroyed any gain it got from using so little power. EDIT: One set of bench…
raspberry pi has terrible power management as well. turning off a core was impossible on previous generations for example. a few years ago rpi was the worst of all sbcs we measured for battery powered usages. this was for an actual embedded product so it wasn’t going to be used either way (ask broadcom for some chips HAHA)
but there is very little reason to use a rpi over other sbcs if you have a remote idea what you’re doing beyond hobby use

#13Would love to see actual security focused hardware/software features, like full OP-TEE, fTPM (or a more ideally a real physical TPM), and similar. For example, so that the OTP isn't the only way to store a disk encryption unlock key.
The existing secure boot mechanisms aren't bad, but allowing for more than one public key hash in OTP would be nice, too.
These kinds of things are expected to be on modern embedded SOCs and SOMs now.

A very small point, but pulling from a feather form factor BOM to compare.
$0.12 for microUSB female connector (rated 1A) $0.26 for a USB-C female (rated 3A). Needs 2 x resistors (I think the power capabilities are the biggest item. If you want to pull higher current from a laptop for development or supply from a wall, you have to switch to USB-C.
I don't think either of these prices are that aggressive - pretty sure the cost comes down at volume.

#16The 8GB Pi 5, at $170 [1], is encroaching on Jetson Orin Nano Super's $240 price point [2]. But the Jetson has a faster CPU (newer a78ae cores rather than a76) and, obviously, a whole-ass GPU.

#17I have bought an rpi at every generation. And I still have yet to find an actual use for them.
Everything they do from a compute perspective is just better with a mini pc or old laptop with a mobile spec chip.
Everything they do from a programmability perspective is just better with a microcontroller specific to the task.
I just don't see the actual market position for these things. They were supposed to be a cheap board, but you can't actually buy them cheaply because the vendors upcharge so much.

I wonder if it would be worthwhile for them to produce both. Well, it will be hard to compare because the design cost doesn’t show up in the BOM, haha.
But it seems like it would be useful nowadays, since some laptop have mostly USB-C connectors, and USB-C to USB-C is pretty common. I’ve never seen a C to Micro. Do they even exist?

A physical TPM with their overall high-quality software support would be awesome.
I've spent far too much time messing around trying to get TPMs working over SPI or I2C to meet security requirements with 4Bs and 5s over the years.
