Because I charge out at $X per hour and the calculations that take my machine 1 hour to do, typically take their machines 3 or 4 hours to do. From an executive level, a lot of clients would rather spend $2k on a cheap throwaway machine than spend say $5K, but then seem fine to have the labor component cost 2-3x as much. I just build the price of the hardware into my hourly rate (which ends up being not very much .. $2 per hour), AU law instant write-off the cost of the machine as tax, tell them they don't need to buy a machine (which they are very happy about), and then everyone is surprised at how fast I can get the job done compared to the in-house teams which have their hands tied.
