At $120? Any software dev in LA with any experience is probably at $75/hour, and they don't have to outfit an entire shop with compressors, lifts, and pricey alignment racks. At $120 in Southern California, you ought to be crowing about the deal you got.
It reminds me when I was a pro mechanic years ago, and the biggest whiners about the hourly rate were doctors and lawyers. Excuuuuse me, Mr. Bills-at-Twice-the-Rate-I-Do?
I mean, you’re not seriously trying to compare capex between an automotive shop and a software dev are you? :-)
My dev machine was about 5k, and I will build another one in another 3-4 years. My tablet was 1.5k. My phones for dev purposes are numerous and run 5-800 each. These get replaced every year or three. My primary laptop was 3k, I will buy another in another 3-4 years. My secondary laptop was 1k, it will probably last 4-5 years. My monitors were 1.5k each. I’m sure I’ll use those for 6-7 years. I have three. My test server was 5k. I will probably build a new one in 5-7 years. My sit/stand desk was 1k, my chair was almost 1k. Etc, etc… All of my tools are expendable on a much shorter time table than your mechanic tools.
Your 10k of snap on tools are good for life.
