The reality is that when I'm at work, I'm logged in to a super beefy server. When I'm at home, I'm logged in to a moderately sized server in GCE. I don't use an IDE, essentially the only apps I use are Firefox, Spotify, and Terminal.
What's holding me back is the screen size. I'll take the biggest screen I can get. More screen == more panes. I absolutely love the 15" inch pro screen. Not sure if I could live with the 13" on the air.
