I almost never use a tripod except to get night shots and fireworks. I went to a seminar over the weekend, and the photographers teaching it said they use their tripods 90-100% of the time, and it's important to invest in a good one.
I guess I knew this- for instance Bryan Peterson mentions in his books he always shoots with a tripod. I know all the professional photographers do it- but how often do the "good" amateurs? It seems like professionals hardly ever shoot handheld (other than wedding photography or something like that).
The idea I got was that you shouldn't cheap out on a tripod. But honestly I've never thought of spending much on one until now. Do you use one a lot? Do you see a big difference in sharpness even in broad daylight?
I was in your situation several months ago. I had read many times about the importance of buying a good tripod and not skimping on $$$ for a tripod. So when the time came for me to shell out money for tripod legs, it took me hours at the camera store debating how often would I
really be using this tripod. I was struggling to convince myself that it would be money well spent, especially since I was already doing well with my current shooting style without a tripod.
For professionals, I think a tripod during the day is much more important than for us "regular folk". Because their goal is to get the best image quality for a particular scene, they'll bring their ISO down to 100 and bring their aperture down to around f/11 - f/16 or smaller. In addition, there may be filters involved as well, especially for folks taking photos of streams / water. All this may necessitate a slower-than-normal shutter speed during the day, thus requiring a tripod. I'm not sure if this would be the case during a bright sunny day (ie. the "sunny 16" rule says that you can use 1/100 sec shutter speed in this situation), but if you're shooting landscapes during the "golden hour" in the AM or PM, then a tripod would work best.
Or, if you're doing HDR, you'll want all 3-5 of your photos to be exactly aligned as much as possible--another reason for a tripod during the day.
At Disney World, I'm always on the run, so a tripod during the day would actually hinder my progress at the parks. Since I'm not trying to sell any of my Disney photos, as long as I can get good, sharp images handheld, then I'm pretty happy without my tripod during the day.
The only time I'd use a tripod during the day is if I'm trying to take a picture of me and my wife together in front of a scenic background. I'll set up a tripod and self-timer so I can be in the picture with her during the day.
So, to answer your question, I think I hardly use my tripod during the day, except maybe for a handful of photos. During the night, I'll use it a lot more, but not to the point where I'm stopping every 10 steps to set up another tripod shot...although my wife would strongly disagree...
