 I ordered a calculator after collecting box tops from some breakfast
 cereal in the late '70s. Then, slim wallet calculators became the rage
 - right about the time, albeit brief, that nylon/velcro wallets were
 "cool".

 It wasn't many years later before the first calculator watches came
 out, my parents had a friend who worked at Hewlett Packard and had one
 of their calculator watches - the LED model with a stylus.

 My black rubber Casio calculator watch had to wait until much later.

 I still have a drawer full of calculators - a couple of HP business
 models including a vintage HP 12c, a couple of HP scientifics, another
 of the CASIO Programmable calculator I used in the early '80s (bought
 off eBay last year and still on the original battery!) and a couple of
 scientific calculators. I keep a solar Casio scientific at my desk,
 mostly because I hate having to look for a calculator app on my
 desktop, and clicking buttons with a mouse feels *wrong*.
