    Probably best to look at it as a competitor to a Xeon D system, rather than any full-size server.

    We use a few of the Dell XR4000 at work (https://www.dell.com/en-us/shop/ipovw/poweredge-xr4510c), as they’re small, low power, and able to be mounted in a 2-post comms rack.

    Our CPU of choice there is the Xeon D-2776NT (https://www.intel.com/content/www/us/en/products/sku/226239/intel-xeon-d2776nt-processor-25m-cache-up-to-3-20-ghz/specifications.html), which features 16 cores @ 2.1GHz, 32 PCIe 4.0 lanes, and is rated 117W.

    The ostensibly top of this range 4584PX, also with 16 cores but at double the clock speed, 28 PCIe 5.0 lanes, and 120W seems like it would be a perfectly fine drop-in replacement for that.

    (I will note there is one significant difference that the Xeon does come with a built-in NIC; in this case the 4-port 25Gb “E823-C”, saving you space and PCIe lanes in your system)

    As more PCIe 5.0 expansion options land, I’d expect the need for large quantities of PCIe to diminish somewhat. A 100Gb NIC would only require a x4 port, and even a x8 HBA could push more than 15GB/s. Indeed, if you compare the total possible PCIe throughput of those CPUs, 32x 4.0 is ~63GB/s, while 28x 5.0 gets you ~110GB/s.

    Unfortunately, we’re now at the mercy of what server designs these wind up in. I have to say though, I fully expect it is going to be smaller designs marketed as “edge” compute, like that Dell system.

    Free for personal use, so yes-ish. That’ll certainly be a deal-breaker for some.

    Realistically, people who are using it for personal use would probably be upgrading to the next LTS shortly after it’s released (or in Ubuntu fashion, once the xxxx.yy.1 release is out). People who don’t qualify to be using it for free anyway are more likely to be the ones keeping the same version for >5 years.

    It looks like it goes away (I went into the settings for one contact, where there’s a toggle to switch back to SMS/MMS).

    Unfortunately, I can’t figure out how to change it back to RCS for that conversation now.

    Also, on a more personal note: the baby blue background is ugly AF. Like actually just heinous. I’d rather it wasn’t there, you get a perfectly good indicator RIGHT ABOVE THE TEXT INPUT FIELD what it’s about to send.

    I recently bought a Boox Palma, which is a phone-size Android device with a real E-Ink display.

    It’s not a phone (WiFi/Bluetooth only, no mobile radio), and with 4-bit greyscale it’s definitely an adjustment to use with a lot of apps (it has per-app DPI & contrast controls to help), but they’ve done a lot of work on the refresh rate to make it feel responsive.

    It even has midrange-phone specs (SD 6xx series CPU, 6GB RAM, 4Ah battery), with full Google Play, so it’s a quite usable Android device overall. Like most modern E-Ink devices, has a CCT warm-to-cool frontlight, so great for night-time use.

    Now would I want to use it as my only, everyday device (if it was a phone too)? Probably not. Could I? Almost certainly.

    Colour E-Ink is still quite limited (in contrast, and resolution), but I expect the patents on that are quite a bit newer and we won’t be seeing so much movement in that area so soon.

    To expand on @doeknius_gloek’s comment, those categories usually directly correlate to a range of DWPD (endurance) figures. I’m most familiar with buying servers from Dell, but other brands are pretty similar.

    Usually, the split is something like this:

    • Read-intensive (RI): 0.8 - 1.2 DWPD (commonly used for file servers and the likes, where data is relatively static)
    • Mixed-use (MU): 3 - 5 DWPD (normal for databases or cache servers, where data is changing relatively frequently)
    • Write-intensive (WI): ≥10 DPWD (for massive databases, heavily-used write cache devices like ZFS ZIL/SLOG devices, that sort of thing)

    (Consumer SSDs frequently have endurances only in the 0.1 - 0.3 DWPD range for comparison, and I’ve seen as low as 0.05)

    You’ll also find these tiers roughly line up with the SSDs that expose different capacities while having the same amount of flash inside; where a consumer drive would be 512GB, an enterprise RI would be 480GB, and a MU/WI only 400GB. Similarly 1TB/960GB/800GB, 2TB/1.92TB/1.6TB, etc.

    If you only get a TBW figure, just divide by the capacity and the length of the warranty. For instance a 1.92TB 1DWPD with 5y warranty might list 3.5PBW.
