The "IT" dept had to spend a fortune re-validating the user requirements for the various applications, documenting and then converting them into a new platform. Obviously a lot of feature creep and previously accepted bugs (no longer accepted now that responsibility was no longer theirs).
A lot of the applications were frankenstein efforts from people over the years - lots of dead code no longer used, no docs etc. As others have mentioned people create mission critical stuff for their project or team, and then leave or be away on extended leave and it breaks etc.
I found the Blink camera was the best for a battery camera in terms of startup on PIR detection. In comparison my newer Eufy and Arlo cameras take a second or two (sometimes more) and have much less battery life.
The downside on the Blink is that you have to buy high end lithium AA batteries
In retirement my dad took to correcting the Britannica- ie fixing facts or crossing out entire debunked articles.
I worked at an isp which serviced their CBR office with a 128k isdn then upgraded to a "2 mbit" PAPL link (a niche product where you used 2 or 4 pairs of directly connected copper which bypassed the exchange).
