See perhaps this 1991 Radio Shack ad (from a 2014 article):

    There are 15 electronic gimzo type items on this page, being sold from America’s Technology Store. 13 of the 15 you now always have in your pocket.
   
    So here’s the list of what I’ve replaced with my iPhone.
    
    * All weather personal stereo, [**US**]$11.88. I now use my iPhone with an Otter Box.
    * AM/FM clock radio, $13.88. iPhone.
    * In-Ear Stereo Phones, $7.88. Came with iPhone.
    * Microthin calculator, $4.88. Swipe up on iPhone.
    * Tandy 1000 TL/3, $1599. I actually owned a Tandy 1000, and I used it for games and word processing. I now do most of both of those things on my phone.
    * VHS Camcorder, $799. iPhone.
    * Mobile Cellular Telephone, $199. Obvs.
    * Mobile CB, $49.95. Ad says “You’ll never drive ‘alone’ again!” iPhone.
    * 20-Memory Speed-Dial phone, $29.95.
    * Deluxe Portable CD Player, $159.95. 80 minutes of music, or 80 hours of music? iPhone.
    * 10-Channel Desktop Scanner, $99.55. I still have a scanner, but I have a scanner app, too. iPhone.
    * Easiest-to-Use Phone Answerer, $49.95. iPhone voicemail.
    * Handheld Cassette Tape Recorder, $29.95. I use the Voice Memo app almost daily.
    * BONUS REPLACEMENT: It’s not an item for sale, but at the bottom of the ad, you’re instructed to ‘check your phone book for the Radio Shack Store nearest you.’ Do you even know how to use a phone book?
   
    You’d have spent [US]$3,054.82 in 1991 to buy all the stuff in this ad that you can now do with your phone.

That US$1600 (in 1991) Tandy 1600 runs a 286 CPU and has a 20MB hard drive, and supported 640×200×16 resolution (720×350 mode for monochrome monitors):

A CB radio can’t actually be replaced by a cellphone, the phone doesn’t actually do voicemail that’s a separate service you’re paying for so it works when your phone dies, it’s also listening multiple different phones etc.

But it’s an add, obviously it’s trying to sell you something not actually be accurate.

Wow, I didn't know that Camcorders were that expensive at the time. That's $2k today according to https://www.bls.gov/data/inflation_calculator.htm .

Replaced yes, but with generally something worse. Enough to get by, just like a swiss knife is enough, but a ful toolbox would be way better. And with the advancement of technology, a current version would be way more palatable.

I have a digital audio player and it’s the size of a matchbox, with removable storage (now with a 512GB catd), and turn on under 10 seconds. And that tape recorder could be replaced with a very small device too. And I still have my casio calculator from college and that’s what I use if I need to if I need to do a series of computations.
