    Angular looks awesome!
    This is going to be a perfect match!
    - Me

    This is terrible - I don't like Angular at all!
    I should just use Backbone for this.
    - Me, a day later

    Dear lord, backbone.dualStorage is horrible! Maybe I just didn't "get" Angular?
    - Me, two days later

    Angular, huh?

    • ~10 days later:
    • This is working really well!
    • Lets test on some older devices!
      • Ouch. Responsiveness?
      • Profiling revealed: Angular.

    • OK: Plain old javascript
      • I can fix this on my own
