You get used to it - playing on a flute with plateau keys now feels really weird to me! As to whether they are better/necessary - depends who you ask. A lot of the best flutes are not available except open-holed, but even some pro flautists play with the holes plugged unless they need the holes for a special effect.
I'd have to diagree with you there, Sarah, as most flutes are available in closed hole spec as well. Even my American Powell is closed hole, and closed holes are seen as very 'beginnery' in the USA. You may have to oder a closed-hole model, but most flutes have it as an option.
I cannot play an open hole flute (not enough stretch between my right hand fingers), and so have to go without the extended techniques that are available to open hole players. That, however, is the only drawback in my opinion. If your hands are big enough/flexible enough, then consider an open hole flute. If however, you would be prone to tendonitis through over-stretching, then a closed hole flute is by far the better option.
