It's only got the "Superseded" notices because it's an old version, if you browse to the latest one in the menu on the left they're not there.

I take issue with a couple of the points made for pagers (and against smartphones).

Security: Pagers are hilariously insecure. It's all plaintext, and it's broadcast nationwide. All you need is $15 for an RTL-SDR dongle and you can receive and log everything. I've seen, first hand, pager messages with embarrassing medical information and the full patient name and address.

Reliability: Since pagers are one-way only, there are no built in means to check whether a page was received. If the doctor is out of range, the page is just silently lost. Cell phone range may be less but you can get an ACK.
