Your email likely is already delivered over a TLS or SMARTLS protected channel. That's not the (only) problem PGP addresses. PGP provides message authentication in addition to encryption.
To take your colleague as an example, his email was cryptographically signed by him. A function that requires his private key, and possibly a passphrase to unlock the key. The signature includes a hash of the message, and requires that private key to generate. On your end, your client hashes the message again and compares the signature. If it isn't identical, someone has tampered with the content. Presuming you met up ahead of time in person or through another trusted channel, and shared public keys, seeing the valid signature also gives you confidence that this email was actually written by the person you expect, and not anyone else with access to their device or account. (If the senders key is still safe anyway.)
Could you elaborate? If John Smith gets a speeding ticket, all other drivers get a video of it in a "Don't be like John" email? There must be so many drivers, so surely it can't be "all" of them.
I don't think Logitech has been a contender for years now. At least for their desktop peripherals. I used to be a fanboy, but had three mice all fail the same way within a year (middle click failed), then my new, expensive keyboard I bought for the office started dropping many keys under my left hand. And I work from home, so the keyboard only had a few dozen hours of actual use on it.
It feels like there are so few options for peripherals that have the features I want, but don't have gaudy LED light effects or an otherwise silly "gamer" aesthetic.
