I'm with Clayton on this one. I have 1/2 windshields on both my Ranger and RZR. The reasons I like them are;
1. Deflects the wind out of my face but allows it to flow over the top quarter of my head giving a bit of a cooling effect (a BIG deal in the South!).
2. When I ride with guys with full windshields, every water hole equals a stop for them to wash the dust off so they can see their way to next stream. No stream means they dump their drinking water on the windshields!
3. I just like the look and feel of the 1/2's - guess it makes me feel more like I'm part of the environment.
If I lived up in the frozen north, I may feel differently...

Before I added a back glass to my Ranger & swapped the full w/s for a half w/s, I was covered in dust espcially on old railbeds. I'd have to wipe the face of my GPS off every 5 minutes.
Now w/ my current setup, there is some dust, but it's greatly reduced. For a day's ride on a railbed, I might wipe the GPS a couple of times.
Mid Sept' I'll put the full w/s back on since on cooler days, the wind on your face is harsh. Due to a late start to winter I was still riding until the 1st week of Jan'. I'll be back riding in April when the snow is gone. I'll wait until May before putting the half w/s back on.
