What I find strange that they still don't have specs for the dimensions and weight... That is something they have been very coy about... https://puri.sm/faq/index.html#faq-Whatarethephonespecs

review of an early phone: "The phone is chonky. I measure it at 15.6 mm thick, 150.2 mm tall, and 75.2 mm wide." https://azdle.net/2019/11/comparing-apples-and-gnomes/ I assume that the specs will change batch to batch. for comparison: iPhone XS: 7.5mm x 143.6 x 70.9 iPhone XS max: 7.7mm x 157.5 x 77.4

Also from the same person, Azdle, further up in this thread:

Nice move from puri.sm At page 15 and 16 there are some M.2 connectors. One has an USB line named USB2_WIFI_D* and the other USB2_4G_D* so I guess these are used for 2 external radio modules (WIFI/BT and 4G). I wonder what these modules are. Will it ship with the same from the devkit (RedPine WiFi/BT M.2 module on SDIO, SIMCom SIM7100E)? Pretty important from a security/privacy standpoint.

The WiFi/BT module is the same. The modem module is BroadMobi BM818; at later batches there will be an option to get Cinterion PLS8 instead too.

Earlier quoted context omitted.

> x200 with Libreboot How safe are those now that the Intel vulnerabilities are known? I doubt hardware that old is getting microcode updates.

You can disable hyperthreading to mitigate a lot of Intel vulnerabilities. Qubes, which is a popular OS choice within the coreboot crowd, does this by default.

But not all of them, right? Some of the vulnerabilities do require upstream microcode updates, and without them, I feel like the risk introduced outweighs any benefit provided by Libreboot.
