I would say yes I can tell a difference but not enough to warrant going 1080 on all videos because it takes longer to open and save files. When I started with the GP I used 1080 but just too much time so I went with the next setting down. Now I prefer the 720 because it offers the 60 fps (per PhotoJoe advice) which actually works better for slo mo shots since I cross paths with many riders and bikinis.

I really notice a difference watching my home originals but not a whole not once they load on youtube.
I can tell a difference but not enough to go 1080 time consuming wise. I figure half the viewers don't use or don't even know how to use the high def setting on youtube anyways.
BTW, I load my videos onto my computer by way of cable. I was removing the SD card but found it damaged the card after so many times. So I just bought a good quality card and leave it in to avoid damage. Those little locking devices on the side of the card are easily damaged. I do the same with my digital camera.
