To me, that makes a lot of sense. Having only one architecture to support and one image to rule them all across the product line is quite a great thing to have.

The other day, there was a person who had a "reddit gold" bounty for the first person who can help them get the Pi 0 online. The person basically couldn't get the Pi Zero on the wireless network. They had no USB-OTG adapter or mini HDMI adapter they could use to debug the Pi Zero. I was thinking something along the line of making the Pi USB port a USB-serial gadget, but it was still cumbersome. The "accepted solution" was to pull out the SD card for the Zero, put it into a Pi3B they had, get the 3B online, and put it back to the Zero. I think that was such a brilliant idea.

Making it easy for users to achieve such tasks is often overlooked by us who "know too much" to not care about the efficiency of the new hardware. I don't think it was an accident that the Pi is so ubiquitous in education: They made a lot of right decisions to make their product easy to use.

PXE booting is sweet. I develop an OS (Crankshaft) for the Pi, and a lot of times it just has been waiting to write a new OS to the SD card, waiting, plugging it in, realizing I forgot to do something, so I had to repeat. Each time it was 15 minutes of waiting. Pulling the card out and putting it back in, especially with the ribbon cable on the way (and a case too) has been really painful. PXE boot is going to solve…

Or you can use the u-boot bootloader[1], and boot a kernel and root filesystem from TFTP, right? [1]http://www.denx.de/wiki/U-Boot

+1 for PoE support

PoE support has always been available with a seperate PoE Hat [0], I found it to be a strange announcement. 0: https://coolcomponents.co.uk/products/pi-poe-switch-hat-powe...

I was confused by that too. "You used to require a separate board to use PoE. Now you... still need a separate board to use PoE." Oh well.

Also, as possibly the only person left who really doesn't care at all about wireless... I'm glad there's a refresh, sure, but... I'm meh. I've been pxe booting my pi3s for a while now.

Now, if it had official "clean" debian support (not "raspian") that would be something!

2GB of RAM would've been more important to me than all the listed changes.

Or even 4G. Would be nice to have a high-memory variant especially seeing that that would require zero changes in the OS unlike most othet hardware variations.

For any problem, there is always someone who could come up with a brilliant solution and makes me feel like a dummy. That is a great idea I haven't thought of!

PS: Upon further inspection, PXE netbooting is already possible on the 3B under the name of "USB booting," it's just not the default in the hardware, and there might be bugs that are fixed in the new version.

The problem is VideoCore, as the Broadcom firmware and closed libraries are 32bit only.

You can very easily† pop in an ArchLinux ARM AArch64[0] in there and notice that you only get a very basic framebuffer, sound is just not working at all, and the bootloader is quite incomplete. So ARMv7 it is for me, even with ArchLinux ARM and in spite of my wish for better FOSS support from Broadcom or in Linux mainline.

† I find alarm much much better as a distro than raspbian as it's incredibly straightforward to install, maintain, and use, while vanilla debian is downright painful.

Still Ethernet via USB 2.0, which means it is not actually gigabit.

I am using a BananaPi for this. It also has a SATA port which makes it handy for a NAS. Processor and RAM are also a good bang for the buck.

As far as I can remember, the system-on-chip architecture limits the maximum amount of RAM to 1 GB (I'll try and find an official source, it's probably somewhere in the BCM283x peripherals documentation).

Not to say Broadcom couldn't spin a newer revision of the SoC with a different internal architecture, but for now it seems that >1 GB of RAM would require substantially more effort than just swapping the DRAM module on the board.
