My friend recently got a job with google. This is where he worked today

Because the only other options are Windows which is also their competitor and Linux which sucks for just about any non-programming job?

This is very true. But if he works on android, he'd have to have Linux

Android is a Linux kernel just like iOS. What is wrong with that?

iOS is Unix not Linux.

My brother said that google headquarters has slides you can use if you don't want to go down the stairs or elevators.

The google campus is a fun place
