How much of our hypercritical knee jerk reactions to change is not about the changes and more about our unwillingness to accept progress.
Relearning UI is frusterating and annoying, but it is a temporary problem. When XCode 4 was launched last summer, the transition away from XCode 3 was horribly difficult. But 6 months later I’ve forgotten that XCode 3 even existed.
Change is hard, but change is good too. Embrace it baby!
