I NEVER paid that for games when I had my Handbrake and Clie! As a matter of fact... I think about the only app I bought was SplashData.
And actually I am very price conscious about soda and beer... oh wait! I never buy beer or alcohol when I'm out because I know darned well that I can buy a whole 6-pack for the price of what they charge for one beer! Soda I just don't drink.
For something like stickers, when you compare it to other apps that are available and more useful.... ya... I have a problem with 1.99 vs .99
Ha... the key word you used was "bought". Of course the apps were "cheaper" to you if you just downloaded a copy and used it, without paying the person that made it. And on those devices it was very easy to just obtain and use a bootleg copy of an app. But that's not a valid counter-argument to the fact that apps are far cheaper today than they were then. You have to compare the price now to the price then.
The sad part i think is that people need to realize that in the long run refusing to pay a mere 1.99 or .99 for a good app or game is only going to hurt them. Because if the people that write good apps and games can't get paid for their time, they will either not make it altogether, or just write something mediocre. The difference in price between .99 and 1.99, when multiplied by the number of people that buy it, can be enough money to make a difference between a very high quality app and a crap app. If you see a decline in quality in the future, you will have a partial reason why.
edit: people also go purely bokers if a developer decides to charge for a major app upgrade (remember 1password doing that? people were furious). Yet those same people likely complain that the developers of many of the apps they use don't ever update them, or do so very infrequently. Guess they just think they should being doing that forever, for free.
