Re: Pi 400 performance please?

Pi 400 would only make sense to me if it was significantly more powerful than the Pi4B, and it isn't. Or if it had a USP, such as a retro computer case design. Otherwise you're better off with a 4B, SSD and a Logitech K400 keyboard, imo. Much the same performance and it's all hidden behind the monit...

Re: RPi4b 2GB to be replaced by 4GB version?

32-bit rPi OS can use all 8GB, iirc? It's just individual processes that are limited to 3GB.

And I think each tab in Chromium can be a separate process? I could be wrong there, I don't use a browser on my Pi.

2GB Pi4s are quite handy as cheap NAS devices.

Re: Some interesting sales and other figures!

They didn't quite hit the spot with the 400 (imo), still popular of course, but this is spot on.

I hope plenty of them get into the hands of kids, rather than just middle aged men!

Re: RPi Pico - Windows support for development.

One way to look at this. A full Pico dev system, with HW debugger, costs $35 (plus tax and postage), or $55 if you want 4GB of RAM.... Agree, and affordability is what matters to get these devices in front of as many kids as possible. Windows stuff can come later, or even be figured out by the comm...

Re: Why does the RP2040 processor have dual cores?

It's a couple of years since I used one, but they used to have dreadfully slow compile times in the Arduino environment even for the simplest program. I gave up using them because it was such a chore. I'm sure they fixed it by now, they were new at the time. ESP compile times on Arduino are still p...

I doubt we would do something that would be such low volume - it's expensive to organise and run that sort of things when you don't have warehouse space or the infrastructure to support it.

You can hack around with it like this

Or use a microcontroller, which boots a LOT faster, with a real time clock breakout board (e.g. DS1307).
