I don't put apps on markets and dont make games around monetization. I'm a hobbyist making a game because I enjoy coding and making the game, so for this discussion I'd consider myself a consumer rather than a developer.
My demographic: 35, male, married, have a 5 year old daughter. I have a solid professional career. I'm on a budget and am very cost:value conscious but do have some disposable income that I am willing to put towards games, apps, dvd/Blu-ray movies etc each month.
I don't mind reward videos, I've used them in puzzle games to get a welcome hint now and then. They are opt in and give me a tangible benefit so I feel they are a fair option rather than just an annoying hassle.
The worst are the full screen videos and pop-ups that interrupt you every couple of levels. If I'm forced to stop and sit through 2 or 3 ads in the first 5-10 minutes its going in the trash regardless of the gameplay.
'Unobtrusive' banners at the top or bottom are far from actually being unobtrusive. They get in the way, they get misclicked. Particularly on apps for kids they are problematic. I try to ignore these ads, but apps that have them don't usually get much play or stay installed long term because it isn't worth the hassle.
I flat out don't do IAP. If the app is good, I may be willing to pay for it out right, but I won't be nickle and dimed on an ongoing basis. If IAP are effectively required to play and progress, uninstall. If IAP are constantly pushed in my face, uninstall. If they are present but just an extra that sit in the background I'll simply ignore them.
I actually dont do much gaming on mobile platforms regardless of monetization scheme, they aren't really my style of games those that I have installed and played through have mostly been puzzle, word puzzle and physics puzzle.
I use a good number of utility, efficiency, organizational etc apps, for these I pretty much only look for free lite/paid premium monetization in which the free version has reduced features and no or very few ads. Most of the time, the lite version does enough I dont feel the need to upgrade, though there have been one or two that I have upgraded.
By far the apps which I am most willing to pay for are those that connect me to a service beyond just the app itself. Pushover and Plex for instance, as well as educational apps and licensed character (Disney, Nick Jr etc) apps and games for my daughter. I am very willing to buy these outright up to $5 if they are good quality, a good experience, and no ads. An exceptional service app may get me up to $10.
