Before anyone goes "OMG I could use it as a desktop" $75 is close to what you would pay for couple year old ~4 faster laptop with broken screen, sodimm and PCIE SSD slots. Quick ebay check shows things like $90 'Dell XPS12 i7-3537U 8gb 128GB SSD broken screen'

Sure but the pi is more fun.

Maybe in the US. In my EU country(Austria) second hand hardware prices are through the roof. There's no way you're getting anything half decent from the last decade for $75.

And then there's the cooling and power consumption difference between a 10 year old system and a RPi. It's not even close.

This is cool. Whats really holding it back at this point is it's use of a sd card. I find that its pretty difficult to use 4gb of ram on a pi practically, and its often bottlenecked by I/O. It might just be my SD card, but executing trivial commands sometimes takes forever and reminds me that I'm in a pi. I've heard ssds can improve speeds a lot, but you still cant boot off usb.

Could this be fixed by setting aside a few gb of RAM for a virtual RAM drive, and run the OS from there?

It's fairly trivial to build an entire OS into an initramfs to run from memory. Also, the poor performance of most microSD cards is primarily due to their flash quality, and designed use case in phones and cameras for external storage. Using a quality thumb drive or SSD over USB 3.0 would yield substantially better performance.

For folks considering running 64-bit on the pi - I don’t think you need 64-bit userland. I’ve been running a 64-bit kernel on my pi with 32-bit userland perfectly fine. The few things that actually need 64-bit (I’m looking at you mongo) run in 64-bit mode via docker. That said, I’m not 100% sure how much memory overhead I have in this setup vs just running the 64-bit userland. Technically there’s a very interesting “…

x86 Linux had PAE mode, where OS could use large memory, but single process was limited to 32bit. There was some performance overhead.

I really wish Microsoft would release a version of Windows 10 (the full version, not IoT) for the Pi 4 so developers could easily test their apps on an actual ARM device. Being able ship a Raspberry Pi 4 preloaded with Windows 10 to developers could bring a huge boost in the number of apps that support Windows on ARM.

Does anyone know if the rPi4 can play HD (1080p) video in a browser smoothly yet? I bought one to use as a media PC after reading that it could play 4K video. Apparently it can’t even do 1080p in the browser though (YouTube etc)

Yes it can do full hd, ever since at least rPi3. Problem here is chromium. Use omxplayer and the rPi4 will do 4k in full glory. I think you can even use omxplayer with youtube somehow. Chromium doesn't even do hardware decoding on x86 desktops, you just don't notice it, because the cpu's are fast enough to do it nowadays.

> Chromium doesn't even do hardware decoding on x86 desktops

Which is a ridiculous waste of energy... :( you notice it too now using Microsoft Teams (Electron) and Google Meet versus Facetime. Eats your battery in no time.

Isn't https://docs.microsoft.com/en-us/windows/iot-core/tutorials/... IOT-Core for that purpose, or am I missing it?

I don't know where you are in the EU but UK refurbishers constantly sell post-lease desktops and laptops on ebay for around £50, shipping to any EU country is usually £10-20 on top of that, if anything.

Like this kind of stuff: https://www.ebay.co.uk/itm/HP-Lenovo-Intel-i3-Dual-Core-i5-Q...

Is plentiful and easy to buy, again - ships anywhere in the EU.

As for the power consumption - I have to disagree again, I have an SFF like this and in idle it uses about 10W of power, 40W under load.

Rpi4 4GB uses 1-3W in idle, and up to 15W under full load. Yes, the numbers for the Pi are lower, but I wouldn't say "it's not even close". It's close enough that I would absolutely consider getting the larger PC instead.

Did they fix the stability issue? Even with a known-good power supply my raspberry pi 3 has been losing power 3-4 times a week at random points.

FWIW, I'm using the official power supply and have never encounter any power issue.

For some reason people seem to really want to use their $75 Macbook USB chargers instead of just buying the official power supply.

OP is asking for full version not just IOT-Core
