I run nodejs server, postgresql db server(configured to use low memory), installed android studio, developing an react native android app on emacs with i3 window manger on a crouton based chrooted debian os. I am really surprised i can do all these without much delay. Chromebook is really working well for me. The only problem is the samsung chromebook i use has only 8 gb of ssd and after all these i have about 2 gb left. I hope google takes the low ssd memory chromebooks in to account.
