I bought my first personal computer 34 years ago ( 1982 IBM PC) with an MX-100 Dot Matrix printer. It was a huge personal expenditure (over $1,500) but I justified it as a mandatory career development need for my career at Accenture. That year I was promoted to Manager so the ROI worked.
I began wondering today what the total amount I have personally spent on computers, expanded memory, hard drives, printers and supplies since that date. This would be a challenging exercise for me to remember and estimate. The number is even bigger if I include my family and any personal businesses. then add to that smartphones (which are computers) and now my Echo smart pen.
I would say the cost of computers alone has exceeded $50,000. The cost of memory and hard drives would be $10,000. The cost of printers $15,000. The cost of supplies $10,000. The smartphone, palm pilot, smart pens, tablets etc. $5,000. I'm sure I have missed some items or underestimated (cost of internet access, etc.).
So - a conservative estimate would be $100K (without accounting for inflation and investment opportunity loss.
What's the moral? Budget BIG for you technology needs.
