This question is altogether too easy for anyone who has bought a laptop or a smartphone in their lives. Other than a house or a car, these are likely to be the most major expenses, at least in the US.
I was relatively late to computer ownership, having gotten my first computer as I was finishing graduate school. As a grad student in the late 80s — early 90s, it was not assumed we would have our own computers. There were computer labs all over campus, and I availed myself of those when typing up my dissertation. Knowing that computer labs would not be part of my future as a professional, I bought my first computer, a Macintosh IIvx. In 1993 the computer cost me $2500, which is almost $5k in today’s dollars. I bought it with part of the proceeds from getting hit by a car, otherwise graduate student me would not have been able to afford it.

Technology has gotten more powerful and less expensive. I could buy a Mac Mini today for $500, and this little puck of a computer is much more powerful than the IIvx I bought in 1993. The only reason I haven’t bought it is because the form factor isn’t convenient, and I already have a powerful laptop that cost me $1300.
Even today, my computers are the most expensive purchases I make outside of a car or house, even though they have gone down in price. But their utility makes them worth the price.
