While that's certainly a concern, let's not forget that Alcantara is very common in high-end sports cars. It's commonly used in endurance racing (24h of le Mans etc).
I have a full alcantara steering wheel in my Mercedes AMG. It's awful, and AMG Private Lounge forums will tell you the same story, it's not uncommon for people to literally go and swap their alcantara-clad wheels in their $100k vehicles for normal leather. Initially it feels amazing when the car is brand new, but you need to keep cleaning it every month or otherwise it becomes this dirty clump of neither pleasant leather, nor smooth material, it's just unpleasant to touch - and after a certain point it doesn't matter how much you clean it, it just looks like an old rag and the only thing you can do is have the wheel re-done. Having a laptop covered in alcantara sounds like the worst idea ever, probably only a notch better than having shiny black piano plastic on surfaces which scratch from just looking at them.
