30% is just so unreasonable that it would be totally understandable if someone would believe this.
Out of picture, I also have a Magic Trackpad (right) and Logitech MX Anywhere 3 (left). I like to switch up my hand movements.
All you need is a regular ~$50 trackball and a regular ~$100 keyboard without a numpad. (You can have an overlay for that, if you need it.)
As someone else pointed out, this new trackball will make you move your fingers (and wrists) significantly off home row. If you do that in one direction or the other doesn't really matter.
If this works better for you than a Logitech or Kensington trackball, sweet, use it. But so far all the reviews are like "I've never used a trackball, but this looks cool". We've had this technology since the literal 1990s guys.
The trackball I don't use for any precision actions. Its useful if I want to hit a tab, or move to the other monitor. But trying to hit small links for example is painful. (That being said I am using the stock bearings, which don't seem to work well)
It was a significant expense for a keyboard, especially being a kit. Albeit my wrists are worth it.
I am not sure why people are so afraid of exposing ports. I have dozens of ports open on my server including SMTP, IMAP(S), HTTP(S), various game servers and don't see a problem with that. I can't rule out a vulnerability somewhere but services are containerized and/or run as separate UNIX users. It's the way the Internet is meant to work.
I would also love to see some photos taken with it.
In other words, if 35% of hn content is positive (or neutral?), compared to reddit and most mainstream social media, it's actually very positive!
Edit: I found the list of blocked subreddits if anyone is curious to see:
https://hlnet.neocities.org/RIF_filters_categorized.txt
Note that it also includes stuff I wasn't interested in at the time, like anime, and only has subreddits up until I quit, around the API ban.
Reddit (or socially generated sites) are really a mixed bag.
Immich put the joy back in photography for me, it's so easy to find anything, even with just searching with natural language.
Being able to scroll to dates with immich is golden. And the facial recognition is on device and works great.
