I think that one actually has an NVMe SSD (one has a SATA drive in that socket). I've not noticed anything about this disk, a great state of affairs. | > ==== fancy new features added to USB after USB 3.0 ==== | | Charging, expensive cables. Somehow charging now involves negotiation (of voltage? of current?) and this seems to require cables to have active circuitry. That makes them expensive. Mind you, sometimes USB C cables are neither expensive nor smart. Or perhaps you are referring to cables that connect DisplayPort or other odd things to USB C / 3.x. These are necessary because new laptops have fewer and fewer kinds of ports. And fewer ports of any kind. | > DRM is mixed into this, often sidelining Linux desktops. | | Netflix seems to work with the Firefox Widevine plugin. It even had a "Do you | want to install this - you might not want to" popup. Interesting. One complaint about cheap TV boxes from Shenzen companies is that they are not authorized to display things like Netflix and YouTube at better than Standard Definition (detailed rules are not in my head). I wonder whether FireFox on them would solve that problem. We use a Xaiomi Mi Box, which is running licensed Android TV. There are a bunch of inexpensive AMLOGIC s905x3 boxes which could then be interesting. (s905x3-b is the same but with a Dolby Audio license; rare and expensive.) Consider, for example, this colourful model <https://www.banggood.com/HK1-Box-Amlogic-S905X3-4GB-RAM-32GB-ROM-5G-WIFI-bluetooth-4_0-1000M-LAN-Android-9_0-4K-8K-H_265-TV-Box-Support-Google-Assistant-p-1608874.html> Comparing with Raspberry Pi 4: - cheaper especially when including power supply and case and SD card. - CPU is a bit weaker, but the hardware crypto is way faster. - Armbian (derived from Raspbian, derived from debian) should be trivial to put on it. - only some have gigabit ethernet - eMMC should be faster than SD - no ability to hook up random signals Some Shenzen boxes are considerably more expensive for reasons I don't understand. Those with s922x or Rockchip rk3399 SoCs, for example. | > ==== support for video-calling and video-conferencing ==== | > | > We just use notebooks for this. | | The advantage of recent notebooks and tablets for this is hardware | acceleration of audio and video CODECs.

I'm semi-underwhelmed with the Rock Pi X I bought: unless you | really need an x86 SBC in Raspberry Pi form-factor, the current Raspberry Pis | are faster and much cheaper than this board's rather insipid Cherry Trail | Atom. Thanks for the report. Linux support for x86 is superb, especially mainstream distros. Cherry Trail is very old. Intel has 90% thrown in the towel on mainstream adoption of Atoms. But they are still milking the old designs. Where Apple has pushed ARM is pretty interesting. Luckily for AMD and Intel, they aren't a chip vendor.
