According to this list, I've spent ~£120 on iPhone apps. Those .59p apps certainly add up after a while.

I tend to think around 75% of the apps I buy are worth paying the asking price for, though I have on occasion bought apps on impulse and never used them again.

Are there any apps that you really think I'm missing or that you never knew about before this list?

If you'd like to find out how much you're apps library has cost you, simply download the 'App Store Expense Monitor' and find out for yourself.

Perhaps post it here as a comment for others to compare?
