probably counting on you to not be someone who would think, "If I keep a slower computer, I could bill for more because the client would pay for the time I spend waiting for my computer.""
And yet, regardless of how moral it is, the calculation seems correct - billing at $150 an hour means things which take longer, get you more money. Two people have claimed that a faster computer will earn them more money, while describing a situation wherein a faster computer will earn them less money. It doesn't make sense.
With your lawyer comparison it's easy to see paper and tyepwriter; are you suggesting that customers know whether contractors are using an Apple M1 or an Apple M3, and have an idea of how much time that ought to change the quote by, and would consider a different contractor based on the computer they are using? I doubt clients have that insight or interest. Are you saying they buy Apple M3 because they are more moral contractors and it's the right thing to do? Even if it is more moral, I find that unlikely to be the reason since the argument was explicitly "it makes me more money" not "it saves my customers money".

I think people would see you upgrading your M1 to an M3 and decide you were being extravagant and therefore charging them too much, and leave for a competitor who is more frugal. Far more than they would decide you were a con artist because you didn't have the latest and greatest. Are you saying that the reason to invest in a new top of the line Apple laptop is to compete on a race-to-the-bottom where you can undercut competing quotes? That also feels unlikely - you could likely do that more effectively with a second hand AMD Ryzen desktop than a new Macbook Pro (something the well-informed customer would know) and that people competing in a race to be cheapest tend to aggressively penny-pinch rather than aggressively spend on the best.
