Nope. Apple computers are for whatever you want to use them for. It's ridiculous to say if you're doing scientific work you should be running Windows. Jobs himself used Mathematica benchmarks to introduce the PowerPC processor at WWDC. Plus back during the dark days when Apple was struggling, there were two groups that continued to favor Macs over PCs: Creatives and scientists. If you went to an American Physical Society convention even back in the 00's, you'd see a lot of Macs.
I'm just telling you in the 90s, and 2000s who made up most of Apple market share WHEN Apple was struggling to stay in business and what kept Apple afloat.
