Well, if he works at a place like I do - my company pays for all of my hardware and software so I never take cost into consideration. My boss wouldn't approve it if I got too outrageous though ($3000 would not be considered outrageous).
Heh, I work for a Fortune 150 company and almost everyone has a macbook pro (at least judging by what I see in meetings and walking around campus). I can't even imagine how much would be saved if everyone used cheap Wintel machines.
I figured there was a use case for it. The price for a laptop goes up exponentially when one of its resources reaches an upper limit. But keep in mind that for that price you could build three desktops with the same RAM and run CI/CD on a redundant distributed cluster (which become necessary for long running simulations, unless you want to keep your laptop at the office all weekend). It's also a more realistic simulation due to system resource and interconnect bottlenecks.
