Posting this running Ubuntu 15.04 on a Dell Inspiron 5520. Everything ran at install. Install was fast. I don’t miss the psychosis that was Windows 8, 8.1, 10 preview. 10 preview is like we threw away the big smelly garbage that was 8 and we only left a few thousand annoying crumbs behind.
I actually don’t mind Windows 8. But I also don’t want to spend 600-800$ every time I need a new laptop. And using older units with a secure free OS would by a nice alternative.
