A monitor is a common thing to start out with, but most people tend not to stick with it and move on to goggles as they are easy to grab-and-go and offer a much better picture; if you have ever tried to look at your cell phone screen while standing in the sun you will know what I mean.
Goggles can be disorienting at first because unlike a video monitor where you are looking down at a screen, goggles suck you in with the immersion; your body feels weird because almost your entire field of view is occupied by the image you are seeing and you find yourself doing stuff like trying to incorrectly center your balance, generally stumbling around like a drunken idiot, and freaking the heck out when that branch you flew by almost hits you in the “face”.
Another problem I have with goggles is flying airplanes that don’t have landing gear (thus need to be thrown). The way you do this is to give it a hurl with the goggles off and fly by looking directly at your RC. This is a problem for me because I wear glasses; I can see fine up close (no problem seeing through the FPV goggles), but as the rc flies away all I see is a blur. I either have to do a juggling act where I fly with my glasses on at first, then while holding the radio take the glasses off really fast, put them somewhere where they won’t get scratched up and put the goggles on, or have a good enough feel for the rc that I can tell what my blur is doing; I generally go for option 2. This is of course not a problem with multi-copters as they can just vertical take-off from wherever you choose to first set them down.
