Not surprised ... Apple hasn't put out a laptop with up-to-date specs for years. I'm a lifelong Mac user and I'm unhappy with their current specs.
Somehow I don't think that their hardware is as much an issue as their price point. As a developer you'd still be a fool (or just loaded with elbow grease) to attempt developing with a chrome book.
Why? I've developed 100% on a cloud VM for years. All I need locally is a browser. Obviously wouldn't work for some things, but as a full stack developer: no problem.
You can even get a full Ubuntu installation in a chroot very easily using a neat tool called Crouton[1]. Crouton lets you jump in and out of chromeos and ubuntu with a keyboard shortcut. I had a very good experience running crouton+ubuntu on my Acer c720, and I imagine it'd be even better on a higher powered computer
