I think the machine is good enough. Portable and Fast. A little short on storage space, but if you don't hog it by huge files or photos then that is not a problem.

Also, I will add the following to the list of apps you should have:

- Flycut (Clipboard Manager)

- GasMask (host file editor)

- Sequel Pro (if you're using MySQL)

- Dotfiles by Mathias Bynens (https://github.com/mathiasbynens/dotfiles)

- Any of your favorite task/to-do list manager.

Feel free to add more.
