I do Android development at work. My workplace equipped me with a laptop that has 16 GB of RAM. It's not enough to have Android Studio open and run the debugger. ADB segfaults because it runs out of memory. Even when I'm not even doing anything at all, Windows already uses a significant portion of RAM available.
Not only for foreigners. I needed an annual ticket only for a specific stretch to go to university, but there's no such option. Instead, I had to pay a ticket for travelling the entire canton.
