First, lets address what causes wind.
The UNEQUAL heating of the earths surface not only modifies air density and creates circulation patterns, it also causes changes in pressure. Meteorologists plot these pressure readings on weather maps and connect points of equal pressure with lines called isobars.The resulting pattern reveals the pressure gradient, or change in pressure over distance. when the isobars are spaced widely apart, the gradient is considered weak,while closely spaced isobars indicate a strong gradient. Isobars help identify pressure systems which are classified as highs,lows,ridges, troughs and cols.
Air generally flows from the cool dense air of areas of highs pressure into the warm,less dense air of an area of low pressure. The speed of the resulting wind depends on the strength of the pressure gradient. A strong gradient tends to produce strong winds,while a weak gradient results in lighter winds.
The force behind this movement is the pressure gradient force. If the pressure gradient force were the only force affecting the movement of air, wind would always blow directly from the higher pressure area to the lower pressure area. However,as soon as the air begins to move, it is deflected by a phenomenon called Coriolis force...this force affects all objects moving freely across the face of the earth. Essentially, things such as ocean currents, or airplane flight paths which would otherwise follow a straight line, end up tracing a curved path due to the earths rotation.
Soooooo...for there to be no wind, the earth's surface would have to be heated by the sun equally. This would increase the surface temp to an extreme that you could not survive.
Want the wind to stop blowing now??

Yeah but it it was not for the wind to blow the fumes from cars and factories away, they would remain over the city and choke it in smog.
If you are unhappy about wind, perhaps you can start a petition Just wait until the other cuckoos protesting against a new definition of planet that exclude Pluto are finished though.

You are asking what the point of wind is? It is like asking what the point of rain is! Wind pushes bad weather along so you have nice sunny days out, so we have food on our plates, so we continue to live. I wouldn't complain about messy hair, put in in a ponytail!

on a warm summer night its great to have. in winter i just have to hate it. but i didn't make this world so its not my place to change the natural laws that apply to it like wind.

well u must have wind
wind is good to move the heat/cold faster
wind cause more fertilization in plants
wind for refreash ur air anywhere ....ur home or local place...
wind is important :)
more then ur hair :P

Perhaps you'd prefer if the atmospheric pressure were just to build up locally? :-)
