I'm not sure I could ever fully adjust to using instant. Rather than not knowing if you're going to have to hit enter because you might have a word in your query that blocks instant, I just hit enter anyways.
And on a different note, I take issue with the people who claim that the "words banned from instant" is a version on censoring. Just hit enter! I certainly know that if I was at work and started to type "fuchsia" and had a slight pause after "fuc", I would be very thankful that google didn't instant-search for the much more common word that starts with "fuc". Quit complaining that you can't get your porn faster! Nothing at all was lost when instant was implemented.
