That figure has actually changed. They had installed 100,000 by the end of 2016. It's over 200,000 now and they are installing 2000 per week.
As for "responsible scientists," that's changed too. Here is a photo of the Curiosity Lander team at Nasa's Jet Propulsion Laboratory on the day of the landing. . . look at their choice of computers. . . and yes, except for one guy in the foreground, they are by a vast majority using MacBooks running OS X.
It's actually a logical choice as the Apple computer is a fully functional UNIX machine capable of running far more software than any Windows computer. . . including all the Windows software.
One of my friends came to the Philippines, with a new IPhone 8+. The difference in the camera of the iPhone 6 and the Iphone 8+ was staggering. Sometimes the human eye cant tell much of a difference. The 8+ camera is head and shoulders above the IPhone 6. There was a huge, VISIBLE difference.
“It’s actually a logical choice as the Apple computer is a fully functional UNIX machine capable of running far more software than any Windows computer. . . including all the Windows software.”
What Apple really should do is come out with “power user” machines including a tower type computer with consumer parts. Right now MacBook “Pros” are quite underpowered compared with the mobile workstations available from Dell, HP and Lenovo. Those machines include Xeons, ECC RAM, and pro level GPUs.
I’m cautiously optimistic about the forthcoming modular Mac Pros, and the iMac Pro. If executed well, they’re a start.
Apple is now the largest company in the world by market cap. It needs to get back to its roots by providing powerful machines for innovators. I’d sure like to see Tim Cook replaced by a technologist.
