Since you posted this in the iPhone and iPod touch Apps forum, I'm assuming you just mean money spent towards apps in iTunes?I was just going through my iTunes purchase history. I added up everything I've purchased since 2008 for a grand total of $732.65. I kinda wish I had some of it back. How much have you spent?
I know how you feel. If an app looks gorgeous, I usually buy it. I love good looking apps. Sadly you buy a few that you regret, but it's worth it (especially when you find great apps).I've spent probably at least $150-$200 on apps.
Some days I just can't help myself. It's addicting, I just want to start downloading apps just to see how they work. It's a real issue lol.
